11InterspeciesRomance in {{Literature}}.
12----
13[[AC:By Author]]
14* Creator/PiersAnthony seems rather fond of this trope.
15** Several such pairings are hinted at but not shown explicitly in ''Literature/{{Xanth}}'', where any two creatures of opposite gender who drink at a "love spring" will fall in lust and (successfully) interbreed. This is the origin of most of the sentient species in the series including harpies (human/vulture), centaurs [[CaptainObvious (human/horse)]], etc. We also have a story where an ogre/human hybrid falls in love with a human/nymph crossbreed, the child of a centaur/hippogryph (eagle/horse hybrid) and all manner of others.
16** In Xanth, EVERYTHING is intelligent (at least to some degree), though not everything can communicate in the human tongue. And in all fairness, Biology is not at all involved. Babies literally arrive via the stork, so there's less squick than it seems.
17*** However, there's the process of summoning the stork...
18** The ''Literature/ApprenticeAdept'' novels feature human/unicorn (the unicorns can shapeshift to human), human/robot, human/werewolf, human/vampire, and human/alien relationships, just to name a few.
19** ''Literature/IncarnationsOfImmortality'' series: human/ghost, human/demoness (three times, one rather {{Squick}}y), human/damned soul. Zane/Luna is an aversion, as they're both human (though he's the current Death).
20* Happens in Creator/AmeliaAtwaterRhodes' novels, particularly in ''Hawksong'', the first novel of her ''Literature/KieshaRa'' series. To prevent war, an Avian (bird shapeshifter) princess and a Serpiente (snake) prince consent to a political marriage to end their generations-long war, but find themselves falling in love. Their child, a wyvern who represents both her parents' shapeshifting powers, in turn [[spoiler: chooses neither an avian nor a serpiente mate, but a wolf woman. This is a good thing as choosing any male mate would lead to her combined powers manifesting very strongly and dangerously in any child she bears]].
21** In her modern day, Nyeusigrube books there are several interspecies romances between vampires, shapeshifters, humans, and sometimes witches, but none are so unusual as Shevaun and Adjila. Shevaun is a vampire and Adjila is a Triste, a particular kind of witch whose blood is almost always poisonous to a vampire. The two species are usually sworn enemies to a point that Triste can be a synonym for vampire hunter. They have been partners for centuries.
22* Creator/JasperFforde:
23** Commander Bradshaw of the Literature/ThursdayNext books is married to Melanie, who's a quite nice woman with conservative taste in dresses, and who also happens to be a six-foot-something ''gorilla''. Bradshaw is rather sensitive about the topic.
24** In the Literature/NurseryCrime books Ashley, an alien member of the force (who at one point mentions that the type of earth creature his species most resembles are several jellyfish stuffed inside a balloon too small for them) becomes quite taken with Mary, and even manages to take her out on a date that she tries fairly hard to avoid. The end result is oddly sweet.
25* Creator/AlanDeanFoster[='=]s books:
26** ''{{Literature/Quozl}}'' is about cute rabbit-like aliens who eventually integrate into human society, and believe in frequent sex anytime, anywhere with any compatible intelligent species as a legitimate means of blowing off steam. The book establishes that once Humanity understood that social more, the Quozl quickly become ''very'' popular company. On the other hand, humankind was the only other intelligent species they'd run into.
27** ''Literature/{{Spellsinger}}'' is set in a world where humans and [[UsefulNotes/FurryFandom anthropomorphic animals]] live side by side including romantic and sexual encounters. Subverted in that, while the Earth-import protagonist feels attracted to an ermine stripper, he's dismayed by his own feelings and never actually goes native enough to join in this trope's fun.
28** The ''Literature/HumanxCommonwealth'' series features a wide variety of alien species. Most of the time the biological and social incompatibilities are treated seriously, although ''mental'' compatibility between some humans and the insectoid Thranx occasionally reaches HoYay proportions. There are some memorable scenes in ''Bloodhype'', however, where a [[ReallyGetsAround particularly flirty]] character discusses ways to erotically stimulate members of other species, intentionally and quite successfully {{Squick}}ing out her companions.
29** In ''Sliding Scales'' a reptilian AA'nn falls in love with the protagonist Flinx. [[spoiler: She doesn't confess her love until already mortally wounded and dies in his arms, prompting one of ''many'' incredible {{Unstoppable Rage}}s and discovering a new LimitBreak technique, more or less a literal application of the DeathGlare.]]
30* Creator/DaveFreer:
31** ''Literature/RatsBatsAndVats'': Ariel the rattess [=NCO=] has romantic feelings for her former human commander, Major Fitzurgh, forged by their teamwork on the frontlines together. Though they have to keep things platonic -- not necessarily because BestialityIsDepraved, but more because she's small enough to fit into his pocket -- they are still quite devoted to each other. [[spoiler: When she gets transferred into a human body via BrainUploading, she wastes little time in jumping him.]]
32** ''Dragon's Ring'' has Meb (a human) who slowly develops feelings for Fionn (a dragon), which are somewhat reciprocated. Due to the fact that dragons can shape change though, with Fionn taking a human form when he's around Meb, she remains unaware of the fact that he's a dragon [[spoiler:for a healthy chunk of the book. Even when the fact is revealed, Meb's pretty alright with the whole idea]].
33* Many of Creator/TomHolt's books feature a character who is really a type of magical being shapeshifted into human form, who fancies a certain human.
34** In ''Nothing but Blue Skies'', the protagonist is a female dragon disguised as a human, who develops a crush on a young human man.
35** The ''Literature/JWWellsAndCo'' series features a she-goblin who shapeshifts into a different beautiful human girl every day and tries to hit on the main character. She mentions that lots of goblin girls like to have flings with humans, and that as shapeshifters, they are open-minded and don't care much about appearances.
36** ''Djinn Rummy'' feature a genie who ''very reluctantly'' finds himself falling for a human.
37* Creator/MercedesLackey's works:
38** ''Literature/TheEagleAndTheNightingales'' has human/birdman relations (along with, "Oh, yeah, people do this all the time back home.").
39** ''Literature/TheFireRose'' deals with the romance between a human and an [[spoiler:involuntarily transformed sorcerer]] [[UsefulNotes/FurryFandom anthro]] [[WolfMan wolf]].
40** ''[[Literature/HeraldsOfValdemar Brightly Burning]]'' contains a [[MindlinkMates lifebond]] between a human and his [[SapientSteed intelligent but non-anthropomorphic horse]]. Thankfully, the author avoids discussing sex.
41** ''Literature/TheObsidianTrilogy'' has Idalia (a human) in love with Jarayan (an elf).
42** In ''Literature/TalesOfTheFiveHundredKingdoms'' a human woman and a male dragon fall in love... while, unbeknownst to them, their best friends (same arrangement) ''also'' fall in love. [[spoiler: Fortunately, a Fairy Godmother can step in with a powerful spell that borders on BodySwap, so you have one human couple and one dragon couple -- both happy.]]
43* Creator/FritzLeiber's novels:
44** ''The Wanderer'' included romance with an off-world female from a feline race. Think serious scratches down the back.
45** ''Literature/FafhrdAndTheGrayMouser'' have non-human girlfriends among their [[TemporaryLoveInterest conquests,]] including a ghoul[[note]]Ghouls of Nehwon seem to be just a race of humans with invisible soft tissues. They look like skeletons but feel like normal humans. Also they used to steal and eat bodies from cemeteries, but seem to have long stopped that.[[/note]] and a sapient rat-girl [[spoiler:who is part human. In fact the rat city under Lankmar seems to be the result of many generations of a merchant family magically shrinking themselves and screwing rats]].
46* {{Deconstruct|ion}}ed in several Creator/HPLovecraft stories that show how squicky such a thing would actually be--e.g. "Facts Concerning the Late Arthur Jermyn and His Family" (an ape) and "Literature/TheShadowOverInnsmouth" (a race of hideous fish-frogs known as the Deep Ones). On the other hand, considering Lovecraft's peculiar attitude towards ''intraspecies'' romance, they could also be seen as not so much a {{Deconstruction}} but just a different brand of FantasticRacism allegory... Let's face it: the guy was squicked out when he discovered that his great-great-grandmother was ''Welsh.'' In a way, this could be seen as a RealLife {{Deconstruction}} of {{Squick}} itself.
47* Creator/ChinaMieville:
48** In ''Literature/{{Kraken}}'', a human man and a female djinni (treated in this universe as fire elementals) have a relationship and a daughter. The reveal comes with the protagonist realising that a photo which he thought showed father and daughter standing by a bonfire was actually a full family portrait.
49** ''Literature/PerdidoStreetStation'': The main character's lover is an insect-woman. Admittedly, she does just have a big insect in place of a head; everything else is human.
50* Tempe O'Kun's furry novels tend to feature interspecies couples as protagonists.
51** ''Literature/SixesWild'' has the hare calling herself "Six Shooter" falling for the flying fox sheriff Jordan Blake. Though Blake's echolocation suggests some insectivore ancestry.
52** In ''Literature/{{Windfall}}'', Siberian Husky Max Saber and otter Kylie Bevy dance around their feelings for each other for half the book before hooking up. And a couple minor characters have a bunny and cat as parents.
53* In both of Nalini Singh's series this is a recurring theme, along with InterspeciesFriendship:
54** ''Literature/GuildHunter'' features a number of [[OurAngelsAreDifferent angel]]-[[OurVampiresAreDifferent vampire]], [[OurVampiresAreDifferent vampire]]-human and human-[[OurAngelsAreDifferent angel]] relationships.
55** ''Literature/PsyChangeling'' features a number of [[PsychicPowers psy]]-[[OurWerebeastsAreDifferent changeling]], [[OurWerebeastsAreDifferent changeling]]-human and human-[[PsychicPowers psy]] relationships.
56* The books by Creator/StrugatskyBrothers feature several: Kammerer/Rada Gaal from ''Literature/PrisonersOfPower'' (Terran human/[[HumanAliens Saraksh Human]]), Rumata/Kira from ''Literature/HardToBeAGod'' (Terran human/[[HumanAliens Arkanar Human]]), and Tojvo Glumov/Asya from ''Literature/TheTimeWanderers'' (Homo Ludens/regular Homo sapiens). They all [[StarCrossedLovers end badly]].
57* Creator/JRRTolkien's ''[[Franchise/TolkiensLegendarium Legendarium]]'' (''Literature/TheLordOfTheRings'', ''Literature/TheSilmarillion'', etc.):
58** There are several known cases of romances between elves and humans, elves and half-elves, and half-elves and humans: Aegnor/Andreth (unhappy StarCrossedLovers), Lúthien/Beren from ''Literature/BerenAndLuthien'' (happily married), Nimloth/Dior (happily married), Finduilas/Túrin from ''Literature/TheChildrenOfHurin'' (unrequited), Idril/Tuor from ''Literature/TheFallOfGondolin'' (happily married), Elros/his unidentified human wife (happily married), Mithrellas/Imrazôr (married until she walked out), their son Galador/his human wife (married), Celebrían/Elrond (happily married), and their daughter Arwen/Aragorn (happily married)
59** A short passage in ''Literature/TheHobbit'' suggests that someone in the Took family tree had married into a "fairy" or elven family, which is given as a possible reason for certain hobbits being far more adventurous than the majority. But this is almost certainly a leftover artifact from before ''The Hobbit'' was dragged into the Middle-earth stories, in which "fairy" means nothing and such a legend would be far more than an inconsequential factoid. The narrator also calls the idea ludicrous and presents it as less a statement of possible fact and more of a slur against the occasionally non-conforming Tooks.
60** However, Tolkien [[WordOfGod pointed out in a letter]] that elves and mortal humans (which include hobbits) must be the same biological species to produce fertile offspring, so the above don't truly count. What ''do'' count:
61*** Melian, a Maia (angel) and Thingol, an elven king. They married and even had a daughter (the above Lúthien), thanks to angelic VoluntaryShapeshifting and Melian giving herself an actual flesh-and-blood body.
62*** Tom Bombadil, an ambiguous "eldest" [[ShrugOfGod something]], and Goldberry, some sort of river nymph. It's unclear what, exactly, Tom Bombadil is, but chances are he's not a nymph. Doesn't really matter for the story, though, especially if we consider that they are both definitely spirits in human form.
63*** It is said that Wargs and Dragons are the demimortal offspring of the demonic Umaiar who chose specific forms to reproduce with mere animals. In the same way that Ungoliant mated with normal giant spiders and brought to the world her monstrous yet mortal spawn, like Shelob. If one thinks about it, Luthien's mother is of the same supernatural species as those demons, and the big differences are on the father's side.
64[[AC:By Work]]
65* During ''Literature/TheAdventuresOfFoxTayle'', Fox is helped along on his journey escaping the lab where he was created and the FBI by a handful of sympathetic humans, including Wanda and Diana. Nothing too serious happens, though.
66* ''Literature/AliceGirlFromTheFuture'':
67** The humanoid alien Iria Guy marries human Tadeusz Sokol, and they have a daughter. However, it's a mild case since the only (visible) major difference between Iria's species and humans seems to be that she has purple eyes.
68** There is the unclear case of Rat's parentage, since he's an arthropod, and also a shapeshifter, and here [[Creator/KirBulychev the author]] got really confused in continuity. But Rat also seems to have a humanoid mother, and he himself states he inherited the shapeshifting from his father. However, there's no definite proof that he was telling the truth or that the Pirate Queen is his real mother at all.
69* Interspecies romance was fairly common and accepted in ''Series/AlienNation'', although the Tenctonese tended to be fairly rough in sex so had to visit clinics to make sure they took it easy on their human partners. One of the {{continuation}} novels explores the idea of Newcomers and humans interbreeding, but it turns out to be [[spoiler:a deformed Tectonese girl produced from an experiment who was mistaken for being half-human for a while due to her single heart and other weaknesses]].
70* Subverted in the short story "And I Awoke and Found Me Here on the Cold Hill's Side" by Creator/JamesTiptreeJr -- humans are driven to have sex with the new and unusual, but in the end receive nothing from the experience except abuse and abandonment.
71* Happens in the ''Literature/{{Animorphs}}'' series:
72** Tobias and Rachel have this -- Tobias is a Human [[ShapeshifterModeLock stuck in the body]] of a hawk who regains the ability to temporarily [[VoluntaryShapeshifting turn back into a human]]. At least one of the books directly addresses the ambivalence both feel about the relationship, including with issues such as Tobias's much shorter lifespan if he stays as a hawk.
73** In addition, Andalites (a centauroid alien species) can use their morphing "technology" to [[VoluntaryShapeshifting change themselves]] ''[[ShapeshifterModeLock permanently]]'' into another species, and two are known to have done so:
74*** [[spoiler:The above Tobias]]'s parents were a Human and an Andalite [[spoiler:(Ax's elder brother Elfangor, in fact)]], and their romance is depicted in ''The Andalite Chronicles''. And as their kid is sort-of half-andalite, his relationship with [[spoiler:Rachel is interspecies regardless]].
75*** In ''The Hork-Bajir Chronicles'', the Andalite Aldrea became Hork-Bajir and married the Hork-Bajir seer Dak Hamee. Her rejection of her own kind was partly motivated by horror when the Andalite war-prince Alloran tried to genocide the entire Hork-Bajir species.
76* In ''The Arabian Nights'', in the tale of ''Hassan of Basra'' or ''Hassan of Bassora'', the titular Hassan is a humble seller in Basra who ends up marrying the youngest daughter of the King of the Djnni, who rules in the Islands of Waq-el-Waq over the other classes of djinni.
77* ''Literature/ArtemisFowl'' plays with this trope in Book 6, when [[spoiler:Holly and Artemis]] kiss and start developing romantic feelings for each other. The rest of the book sees their friendship go through a lot of rough territory thanks to Artemis' machinations but by the end it's left ambiguous.
78** Continued in ''The Atlantis Complex'' where [[spoiler: said mental disorder caused Artemis to have "Orion", a split personality who constantly proclaims declarations of love to Holly. Orion even hints to her that Artemis also has similar feelings towards her but chooses to hide them]]. It's borderline UnresolvedSexualTension now.
79** Played straight with [[spoiler: Turnball Root and his human wife Leonor]]. In fact, [[spoiler: the fact Leonor is dying]] is what causes many events in ''The Atlantis Complex''.
80* In Kurd Laßwitz's early science-fiction novel ''Auf zwei Planeten'' (On Two Planets, 1897), German scientist Josef Saltner is taught the Martians' language by the pretty La. They become man and wife.
81* ''Literature/AuroraCycle'': By the end of the first book, one is developing between [[spoiler:Auri (human) and Kal (Syldrathi)]]. Interestingly, his species [[spoiler:has something they call the "Pull" which will lead people to their soulmates, and he says that as far as he knows no Syldrathi has ever felt it for someone of a different species. But then again, Auri [[TouchedByVorlons isn't a normal human anymore]]..]].
82** At the end of the second book, one begins between [[spoiler:Scarlett (half-human, half-Syldrathi) and Fin (Betraskan).]]
83%%* ''Literature/{{Bearheart}}'': Lilith Mae and her boxer dogs.
84* ''Literature/TheBelgariad'':
85** A discussed trope. Garion is descended from Belgarath and his wife Poledra through their daughter Beldaran. All sorcerers can shapeshift and Belgarath favours the form of the wolf. Garion is horrified to discover that Poledra was actually born a wolf, not human; he is sickened by the thought that Belgarath married a wolf and that the wolf then had babies. Belgarath explains that isn't the case; shapeshifting is actually absolute. Poledra was not a wolf transformed into a human, she was fully human, as were her twin daughters, Polgara and Beldaran. He teaches Garion how to shapeshift to show him the truth of this fact. Belgarath and Poledra therefore subvert the trope in that, in-universe, they are not classified as an interspecies romance. They are both human when in human form and wolf when in wolf form, regardless of what their birth form actually was.
86** The Dryads are an [[OneGenderRace all-female race]] of humanoid beings whose life, and therefore lifespan, is linked to a specific tree. They have reproduce with human males to continue their race, with male children being entirely human and female children being entirely Dryad. An ancient treaty that protects the Dryad forest was established between the Dryads and the humans of the Tolnedran Empire that was sealed by the Emperor marrying a Dryad. Ever since then, the Tolnedran Emperor has always had a dryad wife. As a result, Ce'Nedra, while Toledran, is also a Dryad who is related to the Dryad Queen. Long ago, the Prophecy made sure a treaty was made between Tolnedra and Riva that, when the Rivan King returned, a daughter of the Tolnedran Emperor would become his wife. Ce'Nedra and Garion are therefore bound by treaty to be married, although they genuinely do love each other. It's strongly implied that the original purpose behind the treaty is to ensure the returning Rivan King, a sorcerer, would have a wife who is his equal in lifespan as well as social status: both Dryads and sorcerers can live for hundreds, even thousands, of years, and the Gods have been known to insist that sorcerers have marriages that have no such inequality, [[spoiler:which is why they turned Durnik into a sorcerer when Polgara wanted to marry him]].
87* Creator/SpiderRobinson handles interspecies romance quite logically in "The Blacksmith's Tale" in his ''[[Literature/CallahansCrosstimeSaloon Callahan's Place]]'' series.
88-->'''Mickey Finn (A 6'11'' tall, 600 pound robot/cyborg alien)''': "You do not even know if we are sexually compatible--"\
89'''Mary Callahan (Human):''' "The hell I don't. I can see fingers and a tongue from here; anything else is gravy."
90* ''Literature/CastleHangnail'' has a backstory example: Serenissima's father was a djinn and her mother was a human (with a bit of mermaid in her from another interspecies romance farther up the family tree). According to the narrator, "This sort of thing happens all the time, and nobody pays much attention".
91* Kris, a Terran, and Zainal, a Catteni, in the ''Literature/{{Catteni}}''. It's a plot point that Catteni are biologically very similar to Terrans.
92* Case in point, the ''Literature/ChakonaSpace'' setting, hardly anybody is in a same-species romance, and most of the ones that are have [[{{Polyamory}} a little extra interspecies thing going on on the side]].
93* In the ''Literature/ChanurNovels'' by Creator/CJCherryh, we have an instance of this that is somewhat subverted: [[spoiler: the [[CatGirl hani]] Hilfy Chanur]] falls for [[spoiler: the [[TokenWhite male human]] Tully]] when they are both [[spoiler:being subjected to ColdBloodedTorture and held hostage by the Kif]]. When [[spoiler: her aunt [[TheCaptain Pyanfar]]]] finds out, she is squicked to the point of [[spoiler:having her shipped back to Anuurn for an ArrangedMarriage]].
94* ''Literature/TheChroniclesOfNarnia'' has several cases. ''Literature/TheMagiciansNephew'' mentions the human sons and daughters of King Frank and Queen Helen taking wood nymphs and river nymphs for wives and wood gods and river gods (male nymphs) for husbands respectively. ''Literature/TheLionTheWitchAndTheWardrobe'' tells that Jadis is descended from unions of Jinn (demons/genies) and giants. ''Literature/PrinceCaspian'' has Dr. Cornelius telling of some dwafs disguising themselves as humans and taking human spouses and spawning a few half-dwarfs. And ''Literature/TheVoyageOfTheDawnTreader'' and ''Literature/TheSilverChair'' tell of Caspian X falling in love with the daughter of the star Ramandu.
95* The whole premise of "Literature/CindyAndCragg" is a single-mom getting back in the dating game and the date is with a RockMonster from Saturn.
96* In ''Literature/CodexAlera'', main character Tavi has tense partnership-turned friendship-turned romance with {{Proud Warrior Race G|uy}}irl Kitai. He's human, she's a Marat (basically human, but with enough differences to qualify as a separate species- white hair, abnormally high body temperature, excellent night vision, and the ability to bond telepathically with animals being chief among them). The animal she bonds with: [[spoiler: Tavi. She really wanted a horse though]].
97** Referenced in-verse. Many humans believe that Marat mate with their totem animals. When someone asks Kitai if Doroga (her father) mates with his gargant Walker (think giant badger), Kitai responds "Of course not. Walker would never stand for it".
98* ''Literature/ACourtOfThornsAndRoses'': All over the place between humans and various fae.
99** Feyre with Tamlin at first, before she becomes Fae.
100** In the past, Mor had been in a relationship with Andromache, a mortal queen.
101* ''Literature/TheCrimsonShadow'': Siobhan is the result of one, having an elven father and human mother. Later she is lovers with Luthien, a human man, then has a mutual attraction to Oliver, a halfling man (though it doesn't go far).
102* The ''Literature/DarkestPowers'' series has Chloe Saunders and Derek Souza, the latter of whom is a werewolf. True, Chloe is a {{Necromancer}}, but for all intents and purposes, she is human.
103* Played in an unusual fashion in ''Franchise/TheDarkTower'', where Roland has sex with a [[SuccubiAndIncubi succubus]] in order to get information from it. In a later novel, the same succubus, now in male form, rapes Susannah and impregnates her with Roland's sperm. When the resulting child is born, it's a cannibalistic human-spider hybrid. This is exactly how medieval folklore said [[SuccubiAndIncubi succubi/incubi]] worked. That a demon could never create true sperm or truly mate with a human, so demon children were the result of a succubus stealing a man's seed, turning into an incubus and raping a woman. Succubi/incubi themselves have no "real" gender, being spirits. Also, Rhea and her snake...
104* ''Literature/ADealWithADemon:''
105** ''The Dragon's Bride'' features the romance between a dragon named Sol and the human Briar Rose.
106** ''The Kraken's Sacrifice'' features the romance between a Kraken named Thane and the human Catalina.
107** ''The Gargoyle's Captive'' features the romance between a gargoyle named Bram and the human Grace.
108* Teased in ''Literature/TheDemonAwakens'', the first of Creator/RASalvatore's novels set in his own world of Corona. A centaur comments that he'd only let a woman ride him--and only if he got a ride himself afterwards.
109* In Taylor Anderson's ''Literature/{{Destroyermen}}'' series, it is often hinted and implied that Gunners Mate Dennis Silva and one of the Lemurians, anthropomorphic cat-lemur hybrids, is involved in a relationship. While sexual relations are implied, they are never confirmed.
110** In the fifth book, Walker's Executive officer asks [[spoiler: the engineering officer Spanky]] if he will get in a relationship with a specific Lemurian, referring to it as "going Silva". According to the omniscient narrator, this phrase has become common slang for the humans whenever referring to an inter-species romance with a Lemurian.
111** In the second book a Lemurian [[spoiler:Blas-Ma-Ar, also known as "Blossom" is raped by a human Destroyermen]].
112** Throughout the series, particularly in the first three books, it is shown that the humans are sexually attracted to the lemurian females due to having similar proportions in the relevant areas and a looser sense of modesty than humans. While this largely occurs because there is a lack of human females, the attraction is still noted.
113* There are distinct shades of this in ''Literature/{{Dinoverse}}'', in which middle-school children have their minds cast back in time into the bodies of prehistoric reptiles, mostly dinosaurs. The natives are [[AmplifiedAnimalAptitude more intelligent than you'd expect]], and everyone appears to be the same species, but these are still dinosaurs with kids' minds and actual local dinosaurs.
114** In the first book/two books, a group of Leptoceratops want Canadayce to run away from the Tyrannosaur and join them, Janine quickly becomes close with a native Quetzalcoatlus she calls Loki and half-seriously considers him her 'first boyfriend', and Bertram meets an Ankylosaur who'd just lost her mate and immediately latches on to him, an affection he finds himself returning. These are fairly innocent and for the most part can be interpreted as sudden friendship. Certainly they don't have too much trouble when leaving their new friends to go home. Canadayce "[[AlternateAnimalAffection kisses]]" Bertram, but perhaps because they're incompatible species at the time this does nothing; they kiss more successfully when both are human again.
115** The next books have Patience and an Acrocanthosaurus she names Green Knight. He actively courts her, even presenting her with shiny gifts and nuzzling her at length. When Patience taps into her host body's mind she sees that her host had courted ''him'' and pined after him to no avail - he's interested in ''Patience''. Unlike the previous kids, she earnestly falls for him, too, and is devastated when [[spoiler: he dies]], despondent even when back in her human body and proper time. When it turns out that he's somehow [[spoiler: SharingABody with one of the other returned kids]], they immediately strike the relationship back up. GK's feelings leak over into his human host's mind, so somehow all three are okay with this new situation.
116* Multiple examples from ''Literature/{{Discworld}}'':
117** First and foremost is Angua (werewolf) and Carrot (biologically human, raised and identifies as a dwarf). Their potential children are a plot point in ''Literature/FeetOfClay''. In ''Literature/TheFifthElephant'' it is hinted that Angua also used to have a relationship with an ordinary wolf, implied to be the descendant of a ''yennork'' (a werewolf stuck permanently in one form, in this case wolf).
118** Lupine and Ludmilla Cake: While they're more-or-less the same thing (werewolves), one's a wolf who turns into a wolf-man during the full moon, and the other is a human that turns into a wolf-woman (they more or less meet in the middle). Somehow, they make the relationship work, despite only having one week-in-four per month in which they are the same bodyshape. The secret and beloved dark heart of this meme is that that's very much their affair, and none of our business... or to put it another way, maybe they are [[HeadTiltinglyKinky happier than you think]].
119** There's also the implied relationship between Lord Vetinari (human) and Lady Margolotta (vampire).
120** The Elf Queen in ''Literature/LordsAndLadies'' wants to take a mortal husband, but this is more for political reasons than romantic ones. In the same book there is mention of humans with elf ancestry, which presumably explains [[ElvishPresley Imp Y Celyn]] from ''Literature/SoulMusic'' and [[EarlyInstallmentWeirdness the "elves" mentioned in early books]].
121** It's also been stated (or at least implied) that Nanny Ogg has some dwarfish ancestry, albeit several generations back.
122** Casanunda will romance (or at least boff) any female who'll hold still long enough, pretty much regardless of species.
123** In ''Literature/{{Snuff}}'', there is a one-page mention that a dwarf and a troll have set up a house together in Ankh-Morpork. The same book also has Nobby Nobbs beginning a relationship with a female goblin. Of course, Nobby is also so odd-looking that there's a decent chance he has some goblin ancestry as well.
124** In ''Literature/RaisingSteam'' a wedding between a human and a dwarf is crashed by dwarven extremists, though most of the integrated town thought they were a good match, and it only diminished popular support for the extremists further. They also show the beginning of a relationship between a dwarf and a troll at one of the new train stations.
125** In ''Literature/GuardsGuards'', Errol and the [[spoiler: (female)]] Noble Dragon technically qualify; they may both be dragons, but they are of different species (''draco vulgaris'' and ''draco nobilis'', respectively).
126** In ''Literature/WitchesAbroad'', Greebo is strongly implied to have had sex with a drunken noblewoman at the masqued ball. Greebo is a ''cat'', albeit in human form at the time. (Granted, Greebo is infamous for ''raping'' anything four-legged and female up to and including a ''bear'' ... but this time, the noblewoman evidently cooperated.)
127* In the ''Literature/DoraWilkSeries'' Dora ([[MageSpecies witch]]) and Miron (devil) are having a romance. In the background, ''czart'' (half-devil) Leon is romancing a wiccan (in-story, kind of a nature witch/fairy) and plans to marry her. More cases like this are implied in ''Winner Takes It All'', when [[spoiler:the main characters discover a "school" where {{Fantastic Racis|m}}t Raphael is keeping half-angel-half-magical kids]].
128* ''Literature/{{Dragaera}}'':
129** Piro and Ibronka in ''Literature/TheViscountOfAdrilankha''. Granted, this one is less obvious due to the characters being of different clans of the same race which were manipulated by extradimensional aliens millions of years in the past to be almost the same but have a few traits resembling the native wildlife of the world instead of actual different species, but the severity of the cultural taboos make this count. There are also Zerika and Laszlo, who are Dragaeran and Easterner, respectively.
130** In the later Taltos novels Vlad (human) and Issola minstrel Sara develop an intimate relationship that borders on romantic while not yet (as of ''Hawk'') going all the way.
131* ''Literature/DragonAndDamsel'' focuses on a developing romance between a human woman, Bernadette, and a male dragon, Azrael the Third.
132* Two examples from ''{{Literature/Dragonlance}}'':
133** In ''Literature/TheLegendOfHuma'', the silver dragon Gwynyth falls in love with [[KnightInShiningArmor Huma]], romancing him in the form of an elven female. Once she reveals to him her ruse, he's surprisingly okay with it. It turns from one interspecies romance into another.
134** During the War of the Lance, Gilthanas falls in love with Silvara who unbeknownst to him was Gwynyth's sister. Like Huma, he assumed she was elven. When her nature was revealed, he didn't take it nearly as well.
135* ''Literature/DragonsInOurMidst'' has this in spades, as a major plot point is that several dragons were disguised as humans and took on human spouses.
136* ''Literature/TheDresdenFiles'':
137** ''Literature/FoolMoon'' has a Werewolf/Wolfwere pairing.
138** There's also a human/vampire pairing.
139** A couple was split up when it became a wizard/half-vampire pair.
140** ''Literature/SummerKnight'' has four changelings, the results of human/fae pairings, although the [[RapeAsDrama only background we're told about]] suggests there's not much romance involved.
141** Also the ''other'' wizard/vampire pairing in the series: [[spoiler:Margaret [=LeFay=] and Lord Raith, the parents of Thomas Raith… who's Harry Dresden's older half-brother]].
142** In ''Literature/ColdDays'', it is revealed twins [[spoiler:Sarissa and Maeve, daughters of Mab,]] were Changelings early in their life as well. Meaning their parentage was a Fae/mortal.
143** Somewhat amusingly (and not altogether intentionally) there's a wizard/fallen angel pairing in ''Literature/SkinGame''. [[spoiler:It turns out that the very "intimate", if altogether not carnal, situation of Lasciel's shadow living in Harry's mind made him pregnant with their child — a spirit of intellect, which is apparently what happens in cases like this.]]
144* Being based on a ''TabletopGame/DungeonsAndDragons'' world (see below), there was a surprising amount of angst from [[Literature/TheLegendOfDrizzt Drizzt]] about his eventual romance with Catti-brie -- though admittedly only part of that was due to race. It's done with now, and they're married, though Salvatore has said he's not gonna give them kids.
145** It might have had something to do with the fact that [[WifeHusbandry he knew her when she was ten years old]]...and that he's pushing eighty but would live for centuries (barring accident, violence, or disease).
146** The angst was also partially, at least at first, about the part where Cattie-Brie was the love interest of Drizzt's best student Wulfgar before he had a [[strike:[[DroppedABridgeOnHim bridge]]]] [[DroppedABridgeOnHim cavern dropped on him]] when Drizzt became more popular.
147** Contrast him with Jarlaxle, the [[AffablyEvil charmingly evil]] dark elf rogue, who can and will sleep with anything with two legs, a pulse, and the ability to consent (which is what makes him ''charmingly'' evil, not just evil). And ''maybe'' female sexual organs. He and Drizzt both are noted to be unusual among drow males, who are culturally xenophobic. (Females will sleep with anything, including demons, in the pursuit of power, though there's probably no romance. For that matter, ''intra''racial relations in traditional/Llothian Drow society are rarely all that romantic.)
148*** There's a reason behind the old joke "[[JustForFun/TropersDoItWithoutNotability How the Drow do it?]] He [[spoiler:lies on his back]], she [[spoiler:stabs him with a dagger, as a sacrifice to Lloth]]".
149*** Then again, ''TabletopGame/ForgottenRealms'' got [[http://forgottenrealms.wikia.com/wiki/Crinti Crinti]] (aka "Shadow Amazons"), descendants of southern drow, humans, and half- (surface) elves who looks accordingly and got strong drow cultural influences. The people numerous and strong enough to raid every once in a while [[TheMagocracy Halruaa]], of all places.
150** Like Jarlaxle, [[Literature/TheElminsterSeries Elminster of Shadowdale]] will [[TheCasanova sleep with anything that has two X chromosomes]]. He's hit on ghosts, romanced elves, had a daughter with a song dragon in human form, and [[DivineDate slept with the goddess of magic]] repeatedly.
151** ''Literature/TheYearOfRogueDragons'' has professional dragon hunter Dorn Graybrook fall in love with the song dragon Karasendrieth. As with Elminster, it helps that [[OurDragonsAreDifferent dragons can shapeshift into humans]].
152* Someone keeping track from ''Literature/{{Elcenia}}'''s Rhysel's point of view would assume this was the norm on Elcenia. Though it isn't entirely, it is assumed that a dragon will go through a number of non-dragon mates before settling down with a dragon -- dragons live a ''long'' time.
153* In Creator/AndrewLang's "Literature/TheElfMaiden" fairy tale, the human main character gets married to the titular female elf.
154* ''Literature/TheEmpiriumTrilogy'':
155** The historical figure of Saint Katell was in love with the angel Aryava. Historians consider this relationship to be the main reason the Angelic Wars ended.
156** Rielle develops a love-hate relationship with Corien; she both fears him but finds his offers of worship too appealing to deny.
157* ''Literature/EnchantressFromTheStars'' has Elana, a girl from TheFederation, an extremely advanced society, fall in love with Georyn, a young man from a planet stuck in Middle Ages. This is more justified than many examples, as Their species are extremely similar to the point that Elana is mistaken for a native. However, neither of them could be happy in another world, so [[StarCrossedLovers they part]] once the Federation's expedition departs.
158* In ''Literature/TheFirebringerTrilogy'', what was probably intended as simply a powerful friendship between the unicorn princess Lell and the gryphon warrior Illishar seems to be a bit more than that at times...
159* The ''Literature/{{Firekeeper|Saga}}'' series presents us with the namesake heroine, Firekeeper, and Blind Seer, a Royal Wolf (bigger than most and possessing a sentient mind). Firekeeper wrestles with these feelings for a while but seems to come to terms with them by the end of the sixth book.
160* Creator/OscarWilde's short story [[https://en.wikipedia.org/wiki/A_House_of_Pomegranates#The_Fisherman_and_his_Soul "The Fisherman and His Soul"]] has a TallDarkAndHandsome Fisherman who catches a cute little mermaid in his fishing nets, and releases her when she promises to sing every day so he can catch more fish. Within a few days he falls head over heels in love, and while she likes him back a lot as well, she can't accept his feelings because he has a soul, unlike non-humans like her. And so the young Fisherman begins to work on getting rid of his own soul, succeeding and getting together with her... [[spoiler: Towards the end, however, the mermaid dies and her corpse washes ashore, and the heartbroken Fisherman pretty much drowns himself as he holds her lifeless body.]]
161* The relationship between Jago and Bren in the ''Literature/Foreigner1994'' series counts as this. Because of the social, emotional and psychological differences between the Atevi aliens and humans you can't really call it a romance, but they make sure that all emotional and physical needs are met in their relationship. Besides that, one of the main themes in the series is the difference in psychology and emotional wiring between the two species, and the slow build of their relationship is a very sweet in-universe example of how difficult the interface between the two species can be.
162* The UsefulNotes/{{furry|Fandom}} erotic novel ''Literature/AFoxTail'' has Vulpie (fox, duh) and Polar (wolf). In universe it's not uncommon for male wolves to find vixens attractive but most religions consider it an abomination, and Vulpie and Polar take it a step further by being gay as well.
163* Mostly played straight in Creator/JohnVarley's Literature/GaeaTrilogy, with the Titanide species in particular being (literally!) custom-built for HotSkittyOnWailordAction. Subverted with the Supra variety of angels, which offer sex to human guests as cultural protocol but don't take it any further than a courtship dance and ritualized faux-copulation.
164* ''[[http://www.gutenberg.org/files/29614/29614-h/29614-h.htm The Game of Rat and Dragon]]'' by Creator/CordwainerSmith, who ''really'' liked cats. His character C'mell is also a cat, but she's a genetically-engineered [[CatGirl Underperson, in human form]], and specifically bred to look attractive to humans. Her ''job'' involves seducing VIP visitors in order to learn their secrets, but any actual consummation is forbidden. In "the Ballad of Lost C'mell" she actually falls in love with the human Lord Jestocost, but he's too focused on justice to show affection to anyone. In ''Norstrilia'' she escorts the human protagonist Rod [=McBan=], who's disguised as a cat-person for security, and points out that if they had sex nobody would be any the wiser. However, she seems relieved when he refuses [[spoiler: As a boon, E'telikeli grants them a dream where he spends a thousand years as her cat-man husband]].
165* The protagonist of the ''Literature/GarrettPI'' series has slept with pretty much everything good-looking, humanoid and female, from half-fairy to ghost to demigoddess to space alien ("silver elves"), although he always comes back to Tinne Tate (basically human, perhaps with a bit of elf and/or dwarf blood) in the end. What few species Garrett ''hasn't'' bedded, his associate Morley probably has.
166* ''Literature/TheGirlFromTheMiraclesDistrict'' has a few of those:
167** Lars and Anna, with the former being a werewolf and the latter being a baseline {{muggle|s}} human.
168** Iben, a mortal-turned-immortal HornedHumanoid and his unnamed huldra wife.
169** Implied between Ture, a half-berserk, and Saga, an Asgardian.
170* ''Literature/GoblinsInTheCastle'': In "The Stinky Princess", Violet is princess of a human kingdom and ends up falling in love with Bindlepod, the prince of Nilbog (kingdom of the goblins), who soon returns her feelings. They end up marrying, living in a home halfway between Violet's kingdom and the gates of Nilbog, and having seven children.
171* Averted in ''Goddess by Mistake'', a light fantasy novel wherein the heroine finds herself in an arranged marriage to a centaur (who takes human shape for the actual coupling).
172* ''Literature/HalfPrince'' has a romance between a phoenix and ''a talking'' '''''meatbun!'''''
173* Several examples in ''Literature/HarryPotter'', most of them subject to some form of FantasticRacism:
174** Many of the girls in Harry's year are [[HotForTeacher fond]] of [[OurCentaursAreDifferent Firenze]], but he, of course, does not return their feelings.
175** Hagrid's parents were a human wizard and a giantess. Their relationship didn't seem to last very long, as his mother left when Hagrid was very young.
176** There's also Fleur, who has a veela grandmother and who marries full-blooded human Bill.
177** Quasi-example: Nymphadora Tonks and Remus Lupin (werewolf). "Quasi-" because being a werewolf is not hereditary in this universe, being transmitted by bites (it serves as an HIV allegory), but they're still treated as a separate species in-universe and bigots still refer to their (very rare) offspring as "half-bloods".
178* In Creator/DeanKoontz's urban fantasy mystery ''The Haunted Earth'' interspecies relationships between humans, mythological beings, aliens, and alien mythological beings are both possible and potentially fertile. The main protagonist's partner is a canine demon (or ex-demon) who has an open relationship with their secretary.
179* ''Literature/TheHeroesOfOlympus'':
180** Ella and Tyson, a harpy and a Cyclops.
181** As well as Coach Hedge (a satyr) and Mellie (a wind spirit), who are married and expecting a child by ''House of Hades''.
182* In one novel of ''Literature/TheHighlandsOfAfon'' Theodore, a cat-like alien known as a Taik from the titular Highlands, falls in love with a human named Anna while at college on a multi-species planet. They can't have kids, but his culture is polygamous and she's okay with him taking other wives he can reproduce with, so long as she is First Mother. [[spoiler: Unfortunately her father turns out to be a bit of a bigot, and affiliated with an organized crime syndicate.]]
183* Ultimately the case in John Collier's humorous novel ''[[ExactlyWhatItSaysOnTheTin His Monkey Wife]]'' which is sort of like ''Literature/JaneEyre'' if Jane was a sapient chimpanzee.
184%%* ''Literature/TheHitchhikersGuideToTheGalaxy'': Trillian and Zaphod.
185* In ''[[Literature/HomecomingWalsh Homecoming]]'' by [[Creator/AnneBWalsh Anne B Walsh]] The Lyrror and Mazor can transform themselves into human shape and interbreed with humans. This transformation costs them; Lyrror tend to suffer swelling of the joints, while the Mazor cannot walk without pain. Offspring can freely switch between the forms of the two parents, though their non-dominant form will still suffer the same ailments. However, Lyrror and Mazor cannot interbreed with each other, even if both parties assume human shape. It is never stated what would happen if a lyque and a maqui (Lyrror/human and Mazor/human crosses respectively) were to have sex.
186* In ''Literature/HundredCompanions'' we have TheBrute of the BigBadEnsemble, [[OurWerewolvesAreDifferent Lady Silvermoon]], developing a crush on the (arguable) good guys' TheSmartGuy, [[TheApprentice Sven]].
187* ''Literature/{{Hurog}}'': In ''Literature/DragonBones'', the Hurog family is distantly descended from dragons. Who are sentient, [[BestialityIsDepraved no worries]]. There is also a more recent interspecies romance,[[spoiler: Axiel is half-dwarf, and his parents seemed to be fond of each other]].
188* In Sharyn [=McCrumb's=] mystery novel ''If I'd Killed Him When I Met Him'', Miri Malone, who teaches art at a college and creates art with bathtub toys, hires a lawyer so that she'll be allowed to legally marry a dolphin. The lawsuit never gets anywhere, as she decides on a pre-conjugal visit to the dolphin's tank. This proves to be a very bad idea. [[spoiler:Dolphins will voluntarily mate with practically anything. They also mate underwater.]]
189* ''Literature/InheritanceCycle'': Eragon falls madly in love with Arya, an elven ambassador. Lots of LoveHurts ensue.
190* Robert Silverberg's short story ''Ishmael in Love'' is told from the perspective of a dolphin in love with his (human) trainer.
191* Subverted in ''Literature/TheJenkinsverse'', where humanity is the only species to have ''any'' members who aren't [[{{squick}} squicked out]] by the idea. Sadly for those few, even if they did find an alien who was open-minded enough to try, humans are so much stronger by comparison that any such union would inevitably end in serious injury or death.
192* ''Literature/JohnCarterOfMars'': In the Barroom series the main protagonist is John Carter, an AmbiguouslyHuman from Earth who might be immortal. His love interest is Dejah Thoris, [[GreenSkinnedSpaceBabe a Red Martian princess]]. Most people on Mars resemble humans, except for their different skin colors and laying eggs instead of giving birth like mammals. [[BizarreAlienBiology Somehow, they are capable of having children with humans too.]]
193* Literature/TheJournalEntries are practically MADE of this trope. There are VERY few ongoing relationships in which all people are the same species.
194* In the 1922 novella ''[[http://www.gutenberg.org/ebooks/10337 Lady Into Fox]]'', a British nobleman's wife mysteriously turns into a fox (it's never revealed why), but they continue to live together until she leaves him, because of her now-wild nature. However, she later returns with her children and fox-mate, and they all live together with her ex-husband until she gets killed during a fox hunt and the rest of her family scatter.
195* Art and Myrtle Mumby in Philip Reeve's ''Literature/{{Larklight}}'' books are a product of this, to an extent - their mother is a [[SufficientlyAdvancedAlien Shaper]] in a biologically human body, but it's implied that a few things bleed through (like Myrtle's talent for alchemy). {{Averted|Trope}} with Jack and Ssilissa - only ever one-sided to begin with, and pretty much completely dropped once Myrtle shows up.
196* ''The Legend of Little Fur'' has this as a constant mystery until ''A Riddle of Green''--Little Fur is half elf, half troll. Everyone wonders how an elf and a troll could love each other enough to have a child. The answer: [[spoiler: since Little Fur was going to save the world, a she-wizard captured an elf and a troll and [[AliensMadeThemDoIt kept them locked up together until they loved each other enough]], and then she released them once Little Fur's mother was pregnant]].
197** The eponymous heroine Little Fur herself has a mutual BodyguardCrush with her white cat ally Ginger, who's the feline equivalent of a WhiteHairBlackHeart.
198*** In ''The Mystery of Wolves'', there's a MayflyDecemberRomance between a wolf and a water-sprite/fjord-spirit.
199* Sgt. Bill Booley and Windsweet from ''Legion of the Damned''. Booley is a member of a futuristic Foreign Legion, while Windsweet is a Naa, a cat-like humanoid alien. Booley is taken prisoner by Windsweet’s tribe, romances her, kills her abusive suitor in an ‘honor duel’ and consummates the relationship before escaping the village with the help of the humiliated chieftain, Windsweet’s father. Before the end of the book the two will unite the humans and Naa against far less friendly reptilian aliens and conceive a son. Their hybrid son continues the family tradition by romancing human and Naa alike.
200* Different viewpoints on this is something of a theme in the ''Literature/{{Wayfarers}}'' series. Examples include Human Rosemary and Aandrisk Sissix, and Human Ashby and Aeluon Pei.
201* ''Literature/TheLordsOfCreation'': ''In the Courts of the Crimson Kings'', by Creator/SMStirling. After he [[RescueRomance saves her life]], Martian ActionGirl Teyud matter-of-a-factly takes AdventurerArchaeologist Jeremy off to her cabin. His human co-worker looks ready to protest (to which Jeremy responds with a big grin and The Bird) but doesn't say anything till afterwards; her main objection being that a bust-up between the two -- likely given the cultural differences between Earth and Mars -- might endanger their mission. A Martian doctor who examines Jeremy later seems rather squicked out by the idea of having sex with a human, even as a simple matter of recreation.
202* Creator/PhilipJoseFarmer was famous for writing one of the first erotic stories between a human and an alien in ''Literature/TheLovers''... If you can ''really'' call ''[[{{Squick}} that]]'' "erotic".
203* The ''WesternAnimation/{{Maisy}} First Experiences'' book ''Maisy Goes to a Wedding'' is about Maisy and her friends attending the wedding of [[ADogNamedDog Ostrich]] and Penguin.
204* Justified in Creator/StevenErikson's ''Literature/MalazanBookOfTheFallen'' due to the amount of different races populating TheVerse and NoBiochemicalBarriers:
205** In ''Literature/MemoriesOfIce'', the human commander Whiskeyjack and the millenia-old Tiste Andii Korlat fall in love and have an intense relationship, which has the added benefit of fostering a friendship between Whiskeyjack and the Tiste Andii WarriorPrince Anomander Rake. [[spoiler:Whiskeyjack dies at the end of the book, though, causing Korlat to go on a quest for revenge.]]
206** In ''Literature/MidnightTides'', Trull Sengar, a Tiste Edur, falls madly in love with the human woman Seren Pedac, who reciprocates, but sees little point in showing that, considering their two peoples are at war. They become technically engaged but pretend it's nothing because both think they'll never see the other gain. [[spoiler:They do eventually hook up in a later book, but Trull dies immediately after.]]
207** In ''Literature/TollTheHounds'', Spinnock Durav, another millenia-old Tiste Andii, falls in love with the teenaged human priestess Salind. He is appropriately creeped out by this, but since he can't get her out of his head he goes to find her and talk to her at the end of the book. [[spoiler:It's never told what came out of it, and Spinnock dies at the end of the series in battle.]]
208** Nimander, yet another Tiste Andii, and the [[AllCavemenWereNeanderthals Imass]] Mistress of Thieves Apsal'ara somehow manage to become a couple between books after Apsal'ara is [[spoiler:released from her eternal prison within the sword Dragnipur]] and plops up naked in the throne room in Black Coral. She initially proclaims her intention to stay and advise Nimander but in typical Creator/StevenErikson fashion, they develop a romance behind the scenes by the next book, largely due to Apsal'ara deciding that's how it should be.
209** Tiste Andii WarriorPrince Anomander Rake and the dragon Silanah are heavily implied to at least be FriendsWithBenefits for most of the series. Considering he can [[VoluntaryShapeshifting turn into a dragon]] himself, that's not even {{squick}}y and Anomander Rake is so awesome it's no surprise a dragon is hanging around. The [[Literature/TheKharkanasTrilogy prequel trilogy]] reveals that [[spoiler:Silanah originally joined the Tiste Andii because she was in love with Endest Silann, a minor acolyte then but Rake's chief wizard now, who wants nothing to do with dragons]].
210** Deconstructed with the [[OurGiantsAreBigger Teblor]] [[BarbarianHero Karsa Orlong]] and the slim and short human HotWitch and engineer Samar Dev. Karsa falls in love with her in ''Literature/ReapersGale'', but is acutely aware that he's almost twice as tall and several times as wide as she is and there is a limit to BiggerIsBetterInBed. This being Karsa, his solution is to threaten her with that to drive her away yet somehow keep her around anyway, but somehow, between books, they manage to become a couple anyway, only for Karsa to leave soon again to pursue his civilization-destroying ambitions despite Samar's pleas to stay.
211* This is the premise of tale type ATU 400, "The Man on a Quest for the Lost Wife", of the Aarne-Thompson-Uther Index: the hero is a mortal man, and he marries a woman of supernatural or magical origin: she is a swan maiden in Eurasia; a peri in Iran and Turkey; a goose maiden among the Inuit; a vila (a type of fairy) in Serbia/South Slavic; a samodiva/samovila in Bulgaria; and a neraida in Greece.
212* ''Literature/MarketOfMonsters'': Which couples qualify depends on your definition of "species." Some "unnatural" species like kelpies and vampires definitely do not seem like ''Homo sapiens''; others just seem like humans with supernatural traits, but they're still referred to in-universe as "species." The 2 main couples are 1) Nita (an unclassified unnatural with the power to consciously control bodily functions humans cannot naturally control) and Kovit (a zannie -- looks human but feeds on pain), and 2) Diana (ghoul) and Adair (kelpie).
213* ''Literature/AMasterOfDjinn'': Fatma, who's human, learns her lover Siti is really half djinn.
214* In the ''Literature/MercyThompson'' novels, werewolf males typically marry human females. This is because few women opt to become werewolves (or survive the process of becoming one), and because female werewolves in this series almost always miscarry during their change, making them unsuitable mates for males who want to be fathers. Mercy (a coyote shapeshifter) was once courted by a werewolf, who'd sought a fertile mate with similar powers. Mercy herself is the product of a one-night stand between her human mother and a Native American coyote shapeshifter.
215* ''The Merro Tree'' by Katie Waitman focuses on an interspecies romance between the {{Human Alien|s}} protagonist and an alien species that closely resembles a snake.
216* ''Metaplanetary'' by Tony Daniels (not to be confused with ''Metaplanetary'' by S. P. Meeks) pairs a human with an "emancipated" software program. Their kids exist partially in the "real" world and partially in cyberspace simultaneously, and it's mentioned offhandedly that their baby talk was white noise. (There's a {{Handwave}} about radiation--just go with it.) The intelligent ferret also has a powerful sex drive, which turns towards humans when her original body dies and she [[EmergencyTransformation winds up]] SharingABody with an ArtificialHuman, but she's after everyone, [[DoYouWantToCopulate in a rather blunt fashion]]. (Yes, this book is ''weird''.)
217* It's all over the place in ''[[Literature/{{Reckless}} The Mirrorworld Series]]'', with occasionally [[{{Squick}} squicky]] implications. Jacob and Miranda. Kami'en and The Dark Fairy. [[spoiler: Kami'en and Amelie]]. Jacob and Fox just might count as well, [[{{Animorphism}} depending on how you look at it]]. Valiant has a thing for human girls...
218* In the ''Franchise/{{Mistborn}}'' setting:
219** The kandra are an [[BlobMonster amorphous]] species of shapeshifting spies and infiltrators whose jobs sometimes require intimacy. This becomes a plot point in ''Literature/ShadowsOfSelf'', when it's [[NonHumanLoverReveal revealed]] that [[spoiler: Lessie]] was a kandra, who spent more than a decade married to [[spoiler: Waxillium]], acting as his bodyguard on Harmony's orders. Under happier circumstances, Wayne gets along quite well with the boisterous [[TheLadette Ladette]] kandra [=MeLaan=]; they spend some free time smooching in ''Literature/TheBandsOfMourning''.
220** Humans and [[OurOrcsAreDifferent koloss]] are also apparently able to interbreed, although the koloss mentioned in the later books appear to be significantly more sane and civilized compared with the berserk monsters in the first trilogy.
221* Several examples appear in the ''Literature/{{Mithgar}}'' fantasy series. There are several pairings that a reader would somewhat expect (Elf/Human, Mage/Elf) but some others are a bit more surprising:
222** A Dwarf/Human romance is at one point treated as much more taboo than others (largely due to the Dwarves' strong sense of pride in their race).
223** One sex-addicted human Queen (who was well known for having her lovers executed as soon as they started to bore her) was rumored to have taken a horse to her bed.
224** While Human/Elf pairings aren't taboo, they are generally treated as a bad idea and very tragic due to the human's mortality and the couple's inability to have children. After a somewhat angsty Human/Elf romance is finally consummated the female Elf gets pregnant. Turns out the father isn't a Human, he's actually a Human/Mage/Demon hybrid, making their child half Elf, quarter Human, one eighth Mage and one eighth Demon. This also gives the father the benefit of immortality due to his non-Human heritage. The child's extremely diverse genetics are an important plot point in a later novel.
225** Interestingly it is highly suggested that Chakkia, the female Dwarves, are [[OurDwarvesAreDifferent actually a different species than the Chak (male Dwarves)]]. The Chakkia are never described and rarely seen because they are jealously guarded by the Chak. They never leave the Dwarvenholts and are always veiled when out of their personal quarters. Besides intensely different builds and grace, the [[OurSoulsAreDifferent <light>]] of Chakkia seen by Mages is so different that one specifically believes they must be a different species. In another novel a seer recognizes what the Chakkia are, but never specifies it. One book even has a scene from a Chakkia's perspective which included thoughts about what the secret the Chak didn't know about them was. WordOfGod is that he's not going to explain it.
226** Finally an example that [[BizarreSexualDimorphism technically isn't Interspecies]], but is mostly treated that way in-Universe due to lack of Dracobiology classes: [[OurDragonsAreDifferent Dragons are exclusively male]]. They mate (once every 5000 years) with Kraken, meeting at a large whirlpool. After competing for rights, the Dragons throw themselves into the waiting embrace of a Kraken appearing in the whirlpool, going in order from strongest to weakest. The Dragon and Kraken then mate underwater, sometimes resulting in the [[OutWithABang drowning of the Dragon]]. The offspring are sea serpents which live several thousand years before a metamorphosis into a Dragon or Kraken depending on gender. Most characters have no clue that the three monsters are the same species.
227* Creator/HollyBlack's ''Literature/ModernFaerieTales'': In ''Valiant'', Val, a human, is in love with Ravus, a troll. Whose own father was a human, although apparently troll blood always breeds true.
228* The ''Literature/MoreauSeries'' provides several examples of romances between various types of anthropomorphic 'Moreaus', as well as one between a moreau and a human. In the ''[[Literature/ApotheosisSwann Apotheosis]]'' series, which takes place centuries later in the [[Literature/TerranConfederacy same universe]], Nickolai Rajastan is maimed and exiled for having an affair with a panthress, as interspecies relationships are forbidden by the religion of St Rajastan, his ancestor.
229* ''Literature/TheMortalInstruments'', ''Literature/TheInfernalDevices and the other series in Literature/TheShadowhunterChronicles by Creator/CassandraClare love this trope.
230** Examples from ''Literature/TheMortalInstruments'': Played straight with [[spoiler:Magnus and Alec]]. No [[CampGay pun]] [[StraightGay intended]]. Every witch and warlock is the offspring of a human and a demon (though Word of says that most of these cases are rape, not romance). In ''City of Ashes'' Isabelle is dating a faerie knight. The fey themselves are the offspring of demons and angels. Jocelyn and Luke and [[spoiler:Isabelle and Simon, as of ''City of Lost Souls'']], are in the same vein as Tonks and Lupin from ''Literature/HarryPotter'', with their lycanthropy and vampirism respectively being more like diseases than a genetic trait, though there are born werewolves in-universe. Helen and Mark Blackthorn are half-fey as well.
231*** SpinOff series ''Literature/TheEldestCurses gives some more focus on the relationship between Magnus and Alec.
232** ''Literature/TheBaneChronicles'' shows that warlock Magnus Bane has had quite a lot of interspecies romances. Examples include: Camille (vampire), Imasu (Mundane), Edna (Mundane) and Alec (Shadowhunter).
233** Example from ''Literature/TheInfernalDevices'' include: Will's parents, a Mundane and a Shadowhunter, Tessa with both Will and Jem, Sophie with Gideon, also a Mundane and a Shadowhunter, [[spoiler:Benedict Lightwood and an unknown number of Demonesses]], Magnus and Camille Belcourt, a Warlock and a Vampire respectively, Camille again, with her former lover, a Werewolf, and Magnus again, with Woolsey Scott, also a Werewolf. Jessamine also develops feelings for Tessa's brother, Nate, though this may just be out of her desire to be a Mundane.
234*** Though Shadowhunters and Mundanes aren't exactly a different species, they are different enough to qualify. To make another ''Literature/HarryPotter'' comparison, it is the equivalent of a witch or wizard marrying a muggle.
235* ''Literature/MythAdventures'': Tananda the Trollop is open to dating practically anyone male, provided they're attractive by their own species' standards, rather than limiting herself to Trolls ([[BizarreSexualDimorphism her kind's male counterparts]]). Aahz is implied to have fooled around with all sorts of ladies from dimensions other than Perv, up to and including Sibone, a serpent-bodied Caffiend. Skeeve's first genuine date was with Cassandra, a vampire. This trope ''may'' also be applicable to the HappilyMarried Massha and Hugh Badaxe, assuming Jahks and Klahds are considered to be separate {{Human Alien|s}} species.
236* In Thorne Smith's 1931 novel ''The Night Life of the Gods'', inventor Hunter Hawk falls in love with 900-year-old woodsprite Megaera.
237* In ''Literature/NightWorld'', almost all the main couples are from different species; it's a major plot point throughout the series that Night People keep finding human soulmates despite such relationships being [[StarcrossedLovers forbidden]] by Night World law. The only main couple this doesn't apply to is Keller and Galen, as they're both shapeshifters.
238* In Creator/RobinJarvis' ''The Oaken Throne'', a prequel to his ''Literature/DeptfordMice'' trilogy, a war is being waged between the bats and the squirrels. In the midst of this, a squirrel princess named Ysabelle and a bat named Vespertilio fall in love.
239* In ''[[http://www.amazon.com/One-Who-Waited-Erika-Griffin/dp/1411627164 The One Who Waited]]'', Alice and the Boogeyman, who is a kind of shadow-monster.
240* The main characters in ''The Owl and the Pussycat''. (And in the incomplete, post-posthumously published sequel, they have ''kids''. But this is Edward Lear.)
241* ''Literature/{{Paradox}}'': In ''Even the Wingless'' the Slave Queen, a shapeshifting dragon-like alien, finds herself falling for Lisinthir, a {{Space El|ves}}f and ambassador from a multi-species Alliance that males of her species have been raiding for sex slaves. And [[spoiler: together, they manage to teach the Emperor empathy]].
242* Between Penryn and Raffe in ''Literature/PenrynAndTheEndOfDays'', subtly. It is also hinted at the apocryphal occasion when some angels fell in love with human women. Nephilim ensued.
243* ''Literature/PercyJacksonAndTheOlympians'': Being based on [[Myth/ClassicalMythology Greek Mythology]], there's a lot of it.
244* ''Literature/QuantumGravity'': Human {{Cyborg}} Lila Black gets together with [[spoiler:quasi-demonic]] elf Zal [[spoiler:and demon Teazle]].
245* In ''Radiance'' by Creator/GraceDraven, Ildiko is a noblewoman from the Gauri kingdom and enters an ArrangedMarriage with Brishen, prince of the Kai who would resemble a human if not for his grey skin, sharp teeth and glowing eyes and the fact that his species used ToServeMan.
246* ''Literature/TheRiftwarCycle'': ''Magician'': Tomas and Aglaranna (human / elf), plus Nakor and the Dark Queen (she's human, but it's strongly implied that he's not).
247** Tomas was somewhat mutated by being possessed by the Valheru Ashen-Shugar, a survivor of the race who used to '''''own''''' the elves. He stated that his lifespan had been extended to a thousand years.
248* Sometimes you get interspecies sex without the romance, e.g. ''Rishathra'' in Creator/LarryNiven's ''Literature/{{Ringworld}}'' series (it's a bonding/peace ritual between hominid species, plus an opportunity to get lots of action without the risk of unwanted pregnancies).
249** Averted with species that are ''too'' different, however. The marooned kzinti Chmeee eventually had to invade the Map of Kzin in order to score. "Too different" doesn't have to be that extreme; one humanoid species seldom has ''rishathra'' because few other species can function underwater.
250** Niven also discusses interspecies sex in the short story "Shall We Indulge in Rishathra?", found (along with the Superman essay, mentioned above) in the short story collection ''[[Literature/KnownSpace N-Space]]''.
251** The ''[[Literature/TheDracoTavern Draco Tavern]]'' series contributes to the subject in the short story "Breeding Maze". Another story from that setting, "Smut Talk", also counts, as it explores the possibility of a sexually transmitted AlienInvasion.
252* Girl falls in love with robot is a key element in Creator/IsaacAsimov's ''Literature/TheRobotsOfDawn''. Asimov had first explored this in one of his classic robot short stories, ''Satisfaction Guaranteed'', where a frustrated housewife falls hopelessly in love with an early human-replicant robot. In the anthology notes Asimov expressed surprise that he received a lot of mail from women who shared the heroine's attraction to the robot. He shouldn't have: it is described as the classic romantic hero, attentive, supportive, insanely helpful and physically perfect, and (this being Asimov writing in the '50s) expressing its love only in the occasional passionate kiss.
253* ''Literature/SagaOfSevenSuns'': The [[HalfHumanHybrid product]] of Nira and Jora'h's interspecies romance (and her half-siblings, some of whom are also her cousins, born of the interspecies rape of Nira by Jora'h's brother among others) save the galaxy.
254* ''Literature/TheSagaOfTheNobleDead'' gives us Leesil (a male Human/Elf Hybrid) & Magiere (a [[CuteMonsterGirl female Human/Vampire Hybrid]]). Reformed partners in crime who eventually fall in love. It should also be noted that Leesil's parents also qualified while Magiere's... [[ChildByRape did not]].
255* ''Literature/TheSandmanTheDreamHunters'': The kitsune heroine falls in love with a human man. Fox Morpheus cautions her that these things don't end well.
256* ''Literature/SandpaperKiss'' focuses on cat-girl Lucy, but it isn't until the end of the book that narrator Mark admits to romantic feelings for her. Word of god says this was originally intended as a MayflyDecemberRomance, but the bulk of their relationship was kept in the background for a possible sequel.
257* In Mediterranean, Turkey, West Asian, Iranian and Afghan variants of tale type ATU 425, "The Search for the Lost Husband", and its subtypes, the heroine is a human girl/young woman who marries a husband of supernatural origin: a teriel's (a kind of ogress) son in Kabylian/Berber tales, a dev's son in Turkey, a male peri in Iran and Afghanistan, and a djinn in West Asia.
258* Mostly averted in James White's ''Literature/SectorGeneral'' novels, in which inter-species romance is barely even mentioned, because all of the different sentient races are [[StarfishAliens so biologically different]], to the point of potentially not even having mutually comprehensible concepts of love, romance, and sex. Early novels even suggested that interspecies sexual attraction was viewed as a mental illness, which was dropped later on, probably out of fear that it would be viewed as a [[SpaceJews metaphorically racist]] insult to real-world inter-racial relationships. Very late in the series, it's revealed that a major character has in fact formed a romantic relationship with a non-humanoid being, although in very peculiar and unique circumstances.
259* In ''Literature/SeekerBears'', Ujurak (a grizzly bear) has attracted the attention of Sally (a human), who is helping other people clean up animals from the oil spill. They even hold hands at one point...but then Ujurak turns into a bear in front of her.
260** Toklo also feels temporarily attracted to Tikkani, a female polar bear. Bonus points for grizzly bears and polar bears seldomly having cubs together.
261* In ''Literature/{{Shapeshifted}}'' by Cassie Alexander, the hero Edie has several love interests none of whom are human. There is the (sentient) zombie Ti, the shapeshifter Asher, and Hector, who [[spoiler: actually is Asher in disguise]]. Other humans have romances with vampires.
262* A minor yet important aspect of the ''Literature/SholanAlliance'' series by Creator/LisanneNorman. Though there it's less "romance" as it is "irresistible urge to have sex between permanently bonded telepathically linked couples". This even allows for the production of hybrid offspring, between both male Sholan/female human couples and between male human/female Sholan couples. Sholans are basically CatFolk.
263* The ''Silver Metal Lover'', by Creator/TanithLee, and its sequel, ''Metallic Love,'' in which, you guessed it, girl falls in love with robot.
264* Creator/OlafStapledon's ''[[http://en.wikipedia.org/wiki/Sirius_%28novel%29 Sirius]]'', about a man who creates a super-intelligent dog. Of course turns out badly in the end.
265* In the short story ''[[Literature/HalfALife Snowmaiden]]'' a human starship saves a young woman of an unknown {{Human Alien|s}} species from a starship wreckage. She and [[Literature/DoctorPavlysh the doctor]] taking care of her quickly fall in love. Their problem? She lives at temperatures far below zero, room temperature would kill her. And they don't even speak each other's languages -- TheFederation hasn't contacted her species yet. The title -- her nickname -- alludes to a [[Theatre/TheSnowMaiden 19th century play and an opera]] about a snow girl who fell in love with a human but ended up melted by sunlight. The story ends with a [[TearJerker bittersweet goodbye]] on her home planet. Then they finally dare to touch each other without glass between them (she pulled his hand). She ends with [[SurprisinglyRealisticOutcome a second degree burn]] on her cheek, he gets a superficial frostbite of his palm. Thus they get something to remember each other.
266* In ''Literature/TheSorceresssOrc'', human protagonist Vervain falls in love with her bodyguard Riyu, an orc.
267* In ''Literature/SoulEater'' the human protagonist, Danny falls in love with a monster from another world.
268* Subverted in ''[[http://clarkesworldmagazine.com/johnson_10_09/ Spar]]'', a 2009 short story by Kij Johnson. After the destruction of her spacecraft, a human woman is trapped in a lifeboat with a {{Starfish Alien|s}} survivor, and they have {{squick}}-inducing sex simply because there's nothing else to do. Worse, she has no means of communicating with the alien, so never discovers if the act has any meaning for it; or even if she's having sex with a sentient alien at all and not just their equivalent of the houseplant.
269** The same author first gained renown with an award-winning 1993 short story, "[[http://www.kijjohnson.com/fox-magic.html Fox Magic]]" about a romance between a [[AsianFoxSpirit Kitsune]] and a human, which she later adapted into a novel.
270* In Creator/JulieECzerneda's ''Literature/SpeciesImperative'' trilogy, lampshaded and subverted; one of the alien characters has as his RunningGag happily and frequently teasing the main character, a human woman, about human fictional tendencies in this regard, jokingly accusing her of seeking this very trope, and happily telling her that his species has "No external genitalia". At one point, when he is sleeping, [[ForScience she is tempted to check]]. Czerneda, a biologist by education, tends to give her alien species differing reproductive systems and/or genitalia.
271* ''Literature/SpiceAndWolf'': Lawerence is a human and Holo is a giant wolf who takes the form of a teenage girl ([[LittleBitBeastly + tails/ears]]) for almost all of the time. In Volume 3, after suffering a great psychological blow, she [[spoiler:offers herself to Lawrence, thinking a child they could have together would keep her from being so lonely]]. Lawrence gets to thinking about this as well, and asks Dianna whether there is any record of human-spirit couples. [[spoiler:The original endpoint of the series concluded with Lawerence and Holo marrying and expecting a child.]]
272* Creator/NeilGaiman's ''Literature/{{Stardust}}'':
273** Tristran and Yvaine (half-faerie half-human / star, ya rly)
274** Tristran's parents, [[spoiler:Una]] and Dunstan (faerie / human), obviously. And a side mention of an ordinary cat being knocked up by a faerie cat, producing a smoky blue kitten with color-changing eyes. The other kittens in the same litter were normal, but cats can have kittens by multiple fathers in the same litter.
275* ''Literature/StarTrekTitan'' has the husband and wife team of [[Series/StarTrekTheNextGeneration Will Riker and Deanna Troi]] (Human x Half-human Betazoid). Troi is herself the product of an Interspecies Romance (Human x Betazoid) and has a half-brother who is a Betazoid-Tavnian hybrid.
276* ''Franchise/StarWarsLegends'' tends to feature this trope a lot:
277** Several interspecies romances factor into Creator/MichaelStackpole's and Creator/AaronAllston's ''Rogue Squadron'' and ''Wraith Squadron'' [[Literature/XWingSeries series]].
278*** The most prominent are Gavin (Human) and Asyr (Bothan), who catch quite a lot of flak for their romance, what with them being war heroes and all. Interestingly, it's the Bothan who catches most of this--''even though'' a prominent Bothan politician notes to her that xenophilia isn't unknown among Bothans. It's just that she wants to stay together long term and adopt children--the parts match up, but they can't reproduce.
279*** One of the more memorable examples, played for bittersweet laughs and occurring off-screen in the past, was the romance between Corran Horn (Human) and Chertyl Ruluwoor, a sterile Selonian (an alien species resembling giant, anthropomorphic eusocial otters). On a personal level, they were really compatible -- however, other factors meant they couldn't be together. Corran wanted kids, and Chertyl was biologically incapable of having them. More importantly, a quirk of Corran's bio-chemistry made his sweat acidic enough to penetrate the waterproof fur of his Selonian lover and irritate her skin, while her fur had a similar effect on his own; they effectively sunburned each other whenever they touched.
280*** Because of this experience, Corran also leads into the discussion with pointing out that if one does contemplate dating across species lines, one is obligated to do the research, as things could turn out even worse than intraspecies dating. After all, it's one thing if you (or your partner) want kids and your respective species are biologically incapable of it -- it's another thing entirely if one of the species has biological or cultural traits that could complicate or even ''accidentally end'' a relationship. The examples he gives includes a species being prone to giving love-bites during sex... with ten-inch fangs. That's really something you'd be behooved to learn ''before'' the fact. The unspoken message of the lecture is that interspecies relationships ''can'' work, but it takes a lot of work.
281*** The ''Wraith Squadron'' books had a fair share of this, too, with two of the squadron members -- one Human, one Twi'lek (the woman, naturally) -- getting together
282*** In the Rogue Squadron books, there's also a male Twi'lek, Nawar'aven, hooking up with a female human. This being written by [[BeigeProse Stackpole]], it's completely out of focus.
283*** Among the Wraiths, the team plays a prank and allows the residents of a seedy bar to think that Piggy (the male [[OurOrcsAreDifferent Gammorrean]], who looks like exactly what you'd expect from the name) and Falynn, a human female, are a couple. They're not, and Piggy gently takes her to task for being embarrassed about being seen with him.
284** ''Literature/ShadowsOfTheEmpire'' also had Xizor attracted to and trying to seduce Leia. Xizor is a Falleen, a suspiciously mammalian-looking "[[ArtisticLicenseBiology reptilian]]" species (EU sources have since {{retcon}}ned them to be "reptomammals") whose members can (and do) produce [[LoveIsInTheAir pheromones]] that can ensnare a good chunk of the sentient species in the Galaxy.
285** Between the publication of ''Literature/TheThrawnTrilogy'' (Winter's first appearance) and ''ComicBook/XWingRogueSquadron'' (her eventual husband Tycho's introduction), a few Franchise/StarWarsExpandedUniverse novels hinted at Winter Retrac and Admiral Ackbar being an item. [[{{Squick}} Yeah.]]
286** ''Literature/TalesFromTheMosEisleyCantina'' has two rather creepy couples based on the alien extras seen during ''Film/ANewHope'':
287*** "One Last Night in the Mos Eisley Cantina" stars the humanoid wolf and the giant lamprey-thing, who are given the identities of Lak Sivrak and Dice Ibegon, a male Shistavanen and a female Florn Lamproid, two alien predators who are very much in love with each other and find great physical pleasure in their union. Tragically, Dice is killed in the Battle of Hoth, but as she [[DiedInYourArmsTonight dies in Laks arms]], she implores him to believe in the Force and keep fighting. Lak (who drowns in loneliness) later fights in the Battle of Endor and his X-Wing is shot doen. As he falls to his death [[MyLifeFlashedBeforeMyEyes he has a vision where he first met Dice]] who's offering him the chance to "leave the cantina alone" and be alone in death, or "embrace her" again. He chooses the latter and in the end, both [[TogetherInDeath become force ghosts.]]
288*** "Nightlily: The Lover's Tail" explains that the goatman (Feltipern Trevagg, a male Gotal) and the yam-nosed reptilian (M'iiyoom Onith, a female H'nemthe) are dating when we see them in the film, and that Feltipern drugs M'iiyoom that evening in order to get her into bed. This story emphasizes the lesson from "Wedge's Gambit" about the importance of studying up on other races if you're into dating outside your species with its TwistEnding: [[spoiler: H'nemthe females are culturally indoctrinated to eviscerate and partially devour their lovers after sex, as a response to the [[GenderRarityValue overwhelming majority of males in the species]], and as they see this as an act of love, Feltipern's empathic abilities didn't warn him before she ate him. Classifies as LaserGuidedKarma since he did essentially DateRape her, after all, and was planning on just wooing her and then abandoning her after a night of passion]].
289** There are numerous species that are classified as "Near Human". Which basically means by the proper definition of the word, they're not really separate species at all, just humans with minor visual differences (and occasionally a bit more, like the Miraluka, who have no eyes and see through the Force--and who have a couple of cases of this trope themselves. The birth is usually difficult, though). Given the vast amount of time covered in the EU, it's likely that all the "Near Humans" were descended from regular humans at some point in the distant past. On the other hand, the EU also includes a few romances between humans and distinctly non-human aliens, where it's made clear that they're not capable of reproducing at all.
290** ''Literature/DeathStar'' has two sets. One pairing has no humans in it; it's a Twi'lek woman--who has [[GreenSkinnedSpaceBabe blue skin]] and brain tails--and a Zelosian man, a {{Plant Alien|s}} who looks like a human with green eyes and blood. The other pairing looks human, but one of them is actually a Mirialan, an offshoot of humanity.
291** In ''Literature/TheCrystalStar'', Han Solo met a female Ghostling, a species that is considered, by humans at least, to be incredibly beautiful and apparently most ghostlings feel the same about humans. The problem is that Ghostlings evolved on a low-gravity planet with almost no physical hardships or predators and are extremely fragile by human standards. According to Han any relationship between a human and a ghostling inevitably ends with the ghostling's death. Light touches cause serious bruises to them and even a minor impact can kill.
292** For ''Literature/GalaxyOfFear'', the reason the {{shapeshift|ing}}er alien Hoole is considered the uncle to human Tash and Zak Arranda is because his brother Moloch married their aunt Beryl.
293* In ''Literature/{{Storyteller}}'', Loquastro, the mynah bird falls in love with the fish princess Artemisia. The only reason why couldn't be together is obviously because Loquastro can't swim and Artemisia can't breath air.
294* In the Buddhist/Southeast Asian tract ''Prince Sudhana and Manohara'', human prince Sudhana, from the Panchala Kingdom, falls in love with the ''kinnara'' (half-woman, half-bird) Manohara, from the race of the ''kinnara'' (creatures from Buddhist lore).
295* In Creator/DianeDuane's ''Literature/TheTaleOfTheFive'' series, the first human protagonist gets involved with a fire elemental, while the second takes up with a dragon. Sex definitely does happen, though it tends to be a complicated sort of out-of-body experience.
296* Elizabeth Kerner's ''Literature/TalesOfKolmar'': In ''Song in the Silence'', we have Lanen (human) end up with Ahkor/Varien (dragon). This is facilitated by divine intervention, as [[spoiler:Ahkor is changed into human form after he is grievously wounded in the first book. It becomes a plot point later on when Lanen ends up pregnant. While Varien's shape is human, his blood is apparently not, and the mixture of the two in the kids is slowly killing Lanen before they get some mages to fix it. Later on both Varien and the kids get the ability to shapeshift between forms at will]].
297* In ''Literature/TalesOfTheFrogPrincess'', Li'l, a real, normal bat, meets and falls for [[HandsomeLech Prince]] [[TallDarkAndSnarky Garrid]], a [[FriendlyNeighborhoodVampire vampire]]. Since she was time travelling at the time, he's from a separate time period. When she finds out about his lies, she goes back to her own time. (ItMakesSenseInContext, really!) But vampires live forever, so he turns up, saying that he's [[LoveRedeems genuinely fallen]] [[LadykillerInLove in love with her.]]
298* The relationship between Captain Laurence and ''Literature/{{Temeraire}}'' is, for all intents and purposes, an Interspecies Romance without the sex. Considering that [[HeterosexualLifePartners Temeraire is the focal point of Laurence's life]], [[HoYay well...]] Keep in mind that Laurence is a human and Temeraire is a roughly 90-foot-long dragon.
299* ''Literature/{{Thumbelina}}'' defies the trope, courtesy of Thumbelina herself, who is wooed by a toad, a scarabee and finally a mole. She narrowly escapes all of them. She gets closer to playing it straight with the swallow, who actually pines for her, as she goes off to marry a fairy prince - which, it turns out, is as close as Thumbelina gets to someone of her own species.
300* ''Literature/TortallUniverse'': Aly and Nawat from the ''Literature/TrickstersDuet''. She's human, he's a crow, but crows in this universe can shapeshift into humans if they want. The short story "Nawat" follows up on the difficulties that arise from this.
301* There's a lot of this in ''Literature/TheTwilightSaga'', especially concerning Bella.
302** We also have a multiple-case scenario here, if you remember that:
303*** 1) Edward is (up to some point) a living corpse (making Bella suffer from a severe case of necrophilia in the 4th book and thereafter).
304*** 2) Edward is 117 years old (making him 100 years older than Bella, who is a 17-year-old girl at least on the first 3 books).
305** Though by the end of the series, [[spoiler:Bella is a vampire too, so this no longer applies to her and Edward]]. But then [[StrangledByTheRedString we're told]] [[spoiler:that there's going to be a future romance between their [[HalfHumanHybrid half-vampire, half-human daughter]] and shapeshifter-previously-thought-to-be-werewolf Jacob]].
306* In Creator/WenSpencer's ''Literature/UkiahOregon'' series, Ukiah's relationship with Indigo and Atticus' relationship with Ru are this, as Ontongard Breeders aren't technically human, but since they're HumanAliens it's not obvious to bystanders. The fact that both relationships are ''interracial'' has caused them a bit of difficulty, though. (Atticus and Ukiah are half Cayuse, half alien, Indigo Zheng is Russian/Chinese, and Hikaru Takahashi is Japanese-American.)
307* ''Literature/{{Uplift}}'':
308** In ''The Uplift War'' there is a (partially symbolic) marriage between Robert, son of the (human) governor of Garth and Athaclena, the Tymbrimi ambassador's daughter, though they mostly did it to solidify their species's alliance and both expect to find mates of their own species later. Partly due to the Tymbrimi's extremely humanoid appearance, Robert was seriously attracted to Athaclena for a while, though she deconstructed this trope by pointing out that it wouldn't actually work between them, let alone result in offspring.
309** Male [[SapientCetaceans neo-dolphins]] have a tendency to hit on human women. Sa'ot, for example, in ''Startide Rising''.
310** Interspecies marriage is oddly invoked in ''Infinity's Shore'', when the human Rety rescues a male urs from being eaten by carrying him in her tote bag. Female urs carry their (much tinier) husbands in their pouches, so yee decides Rety is now his wife. She seems fine with that, but it isn't clear whether or not he's actually become attracted to her.
311* Played straight and taken seriously in Ann C. Crispin's ''Voices of Chaos'', where the human female and [[CatGirl cat-alien male]] leads end up in a romantic (and sexual) relationship. Really, considering that it's set in a series whose premise is fostering interspecies understanding and universal goodwill among a cooperative league of friendly alien nations, the only surprise is that it took until the sixth book to do it.
312* ''Literature/VorkosiganSaga'': Miles Vorkosigan's on-again/off-again relationship with [[SuperSoldier Taura]] should count (despite the AbsentAliens setting in the series, she is at least as far from Human as a Drow is). Leo Graf's and Bel Thorne's respective marriages into Quaddie society also apply.
313* The children's story ''Literature/TheWainscottWeasel'' includes a male weasel who falls in love with a female striped bass. [[spoiler:At the end, the fish has to say good-bye because humans are cutting out the pond to the ocean to drain it, meaning that she will be carried out to sea.]]
314* In ''Literature/TheWarGods'' series by Creator/DavidWeber, there are 5 races of man: Human, elf, dwarf, hafling and Hradani (filling the role of orcs). All of them can interbreed, but many of the resulting children are sterile. However, each race evolved from baseline humanity in different ways. Hradani and dwarf are more or less true evolutions and are biologic changes to how they tap the magic field. (Both live longer at the cost of reduced fertility and ability to do magic or psonics while dwarves get rock shaping skills and Hdrani become bigger and stronger and are more able to use the magic field to supplement their strength). Haflings are pretty much mutants caused by the last wizard war. Elves though were not part of a subrace as such until the original wizard war ended and secondary casters whose powers are innate and didn't require extensive training to unlock were found to be too dangerous to have their power. They agreed to undergo a spell to change how their set of genes tap the magic field so that they lose their magic but gain immortality. As such half-elves are non-sterile, live 400 years, and there is an entire nation run by half-elves calling themselves the Purple Lords. If a half-elf breeds with an elf or another half elf, the children are half-elves, but if they breed with a human their children are just slightly longer lived than most humans. Elf-dwarf is mentioned as a very sad affair. Half-dwarves are non sterile and, resulting in a lot of mixing with the Empire of the Axe, having dwarves with more than a bit of human blood (resulting in folks having most of the dwarven skills but little shaping abilities) and humans that are a bit shorter than normal due to dwarf blood. Human-Hradani hasn't been seen in ages, but Wencit testifies it's very good they are sterile. Like all half humans they have the potential for wizardry or psonics, at the same time they have the Hradani ability to tap the magic field, resulting in a far higher number of powerful wizards being half-Hradani. It's hinted that wild wizardry may be connected to the Hradani ability.
315* ''Literature/WetGoddess'' is a story of a romance between (human) college student Zachary Zimmerman and a bottlenose dolphin Ruby. Due to the RealLife setting, also counts as BestialityIsDepraved.
316* In ''Literature/WhoCensoredRogerRabbit'', humanoid Toons usually date humans or other humanoid Toons. This makes Jessica marrying a "[[FunnyAnimal barnyard]]" like Roger all the more suspicious. She'd only dated humans and humanoids until him. Her previous boyfriend was Rocco [=DeGreasy=], her husband Roger's employer.
317* In Creator/EDBaker's ''Literature/TheWideAwakePrincess'', an attempt to rescue Lizette backfires because she actually ran off with the ogre, because he made her laugh.
318* Subverted slightly in ''Literature/WildCards'' wherein there was a human/centaur sexual relationship. The subversion comes from the fact that Finn the Centaur was once entirely human, but the Wild Card virus turned him into a centaur. Brain Trust/Tachyon [human/Takisian], plus Tachyon also had many other relationships with human women, including one which resulted in HalfHumanHybrid child (mentioned as deceased) and grandchild. Popinjay also had a Takisian wife. Then again, Takisians are [[HumanAliens essentially human]].
319* Carmilla and all her more-or-less human entourage, in the Literature/WhateleyUniverse. In fact, with a major-league lust demon for a father and a [[HalfHumanHybrid human/Deep One hybrid]] mother, Carmilla is also the ''result'' of one of those... and from what we've seen of her dad since he showed up in the stories, which basically paint him as a devilishly charming rake with some trouble keeping his tentacles to himself who honestly dotes on his only daughter, romance may well have actually figured into it.
320** Aside from the above, we've also seen hints at possible romance between one or two of the students and members of the local tribe of lycanthropes, and of course there are plenty of mutants whose mutations have forced them into more or less inhuman forms with little hope of reprieve. (The technical term is [=GSD=], for 'gross structural dystrophy' -- 'gross' in the sense of 'overall', mind you.) While the latter may still be technically and legally human, speculations about their potential present or future love-life (such as the Fury Twins idly musing on their chances of finding a boyfriend) necessarily do invoke this trope.
321* ''Literature/TheBookOfDragons'': In "Literature/WhereTheRiverTurnsToConcrete", the main character, who's [[spoiler:a river dragon spirit bound in human form]], forms a relationship with a human woman.
