!!Tropes featured in this work:

* AccidentalMarriage: Owing to human/elf customs differing.
* AlwaysChaoticEvil: The oni and their subraces. [[spoiler: Except the tengu]]. Half-oni are more complicated. All the ones we meet are criminals, yes, but it's treated as [[NecessarilyEvil a matter of survival]], and due to massive abuse by the oni they have a mass FreudianExcuse.
* AlwaysSomeoneBetter: Younger elves have to deal with this constantly. Not only is anything they do likely to be compared against the work of some master in their craft who was born thousands of years before, there's a good chance that said master is ''still alive'' and still producing, making it virtually impossible for new blood to get out of their shadow. One subplot in ''Elfhome'' was a group of doubles (Elves with double-digit ages) who moved to Pittsburgh so that they would have a chance to make their mark in their chosen crafts.
* AndNowForSomeoneCompletelyDifferent: Tinker and Windwolf don't appear in ''Wood Sprites'' at all. The focus characters are two of Tinker's sisters on Earth who she's never even heard of, much less met (They, like Tinker herself, were born from embryos implanted into foster mothers), and their struggles against their biological mother's evil step-relatives, who were briefly mentioned in ''Wolf Who Rules'' but had not appeared before. ''Project Elfhome'' is a short story collection about characters of secondary importance to the first three novels if they explicitly appeared at all.
* AnxietyDreams: Tinker has them.
* BackgroundMagicField: This is how Elfhome's magic is powered. [[spoiler:And it can leak into Earth and pool in certain locations, which is how the exiled Skin Clan elves have stayed alive all this time.]]
* BadDreams: Tinker has them after her kidnapping.
* BalefulPolymorph: By magic, of course.
* BodyguardBetrayal: ''Sekasha'' are expected to put down their ''domana'' overlords if they go off the reservation. This actually happens in ''Wolf Who Rules''.
* BodyguardCrush:
** Elves consider it to be socially acceptable for ''domana'' nobles to take lovers from their ''sekasha'' bodyguards -- even if the ''domana'' in question is already married.
** [[spoiler:When Oilcan is turned into a ''domana''-caste elf, he hires his ''sekasha'' lover to be his First -- as he knew she would reject a marriage proposal and this was a socially acceptable alternative to allow them to be together]].
* TheCavalry: Elves save Oilcan and Tinker from imposters at a RoadBlock.
* ChildProdigy: Louise and Jillian.
* CloseKnitCommunity: In ''Elfhome'', especially, what they are aiming for for Pittsburgh.
* ContemptibleCover: The series is unfortunately plagued with awful-looking, and often inaccurately lurid, covers. It starts in earnest with ''[[https://images-na.ssl-images-amazon.com/images/I/71PkMaomM3L.jpg Elfhome]]''. However, despite how bad the covers get, they all actually do depict a scene from the book.
* {{Curse}}: A plague of bad luck is supposed to be impossible.
* DamselInDistress: Tinker contemplates this trope in the opening of ''Tinker''.
* DirtyBusiness: Windwolf really hopes that there are no [[spoiler:oni children]] to be massacred with the rest.
* DistressedDude: Windwolf in the opening of ''Tinker''.
* DreamingOfThingsToCome: Lain thinks she does. Tinker's dreams also show signs of this. [[spoiler:Esme's prophetic dreams led to her changing her major to astrophysics and becoming one of the captains in the colonization effort, all to protect Lain. Since this particular talent is supposed to be passed from mother to daughter, it's not surprising that Tinker has the gift too. As does her grandmother and at least one other of her siblings, Louise.]]
* EvilAlbino: The elves believe this, thanks to the last emperor of the Skin Clan, who was albino and who had thousands of slaves killed in experimentation for spells to fix his poor eyesight, among other atrocities. [[spoiler:And he's ''still alive'', Esme and Lain's stepfather, and the BigBad.]]
* [[EvilStepmother Evil Stepfather]]: Esme and Lain's stepfather is the BigBad. Can't get much worse than that.
* FantasticRacism: Oh yes. Pittsburgh has humans, elves, tengu and half-oni, and every group has a certain amount of contempt and/or outright hatred for some or all of the others. Even within the elven race as a whole there is this between clans.
* GadgeteerGenius: Tinker.
* GenderBlenderName: Tinker's birth name is Alexander Graham Bell Dufae. This causes a great deal of confusion among those people who only know her name when they're looking for her, since they think they're looking for a man.
* GenocideDilemma: What to do with [[spoiler:the oni]].
* HalfHumanHybrid: Besides plenty of half-elves, there are the entire Tengu species, thanks to evil magic, and the half-oni.
* HardLight: [[spoiler: The Tengu's wings.]]
* HonoraryAunt: [[spoiler: Lain, who turns out to also be Tinker's real aunt.]]
* HonorBeforeReason: Windwolf.
* HufflepuffHouse: The Water Clan. We know that they ''exist'', but while the Wind, Stone and Fire Clans have all contributed major characters, the only Water Clan elf to appear has only featured in a couple of side-stories contained in ''Project Elfhome'' and is implied to be ''very'' atypical of the clan.
* IGaveMyWord: Tinker admits to herself she would have followed through.
* InterdimensionalTravelDevice:
** The hyperphase gate functions as this.
** [[spoiler:The Skin Clan succeeded in breeding a caste of elves to function as this]].
%%* ItWasAGift
* KidnappedScientist: The NSA agents from the first book came to Pittsburgh to warn Tinker that someone -- [[spoiler:later revealed to be the oni and Skin Clan]] -- has been kidnapping and killing scientists who understand the science behind the hyperphase gate.
* LackOfEmpathy: A dominant trait of the [[spoiler:oni]].
* LimitedAdvancementOpportunities: The opportunities for promotion among a domi's ''sekasha'' aren't so much limited as virtually nonexistent. Rank is determined entirely by the order in which they are hired, so a ''sekasha'' who is not hired as First right from the start cannot hope to obtain the rank of First unless either everyone senior to him dies, or his domi dies and he gets hired as First by someone else. This is the reason why very few domana have more than one Hand (five) of ''sekasha'', as a ''sekasha'' hired as second or higher Hand has no real hope of ever achieving the rank of First Hand, let alone First, so as a rule only those domi important enough that the prestige of being in his/her service at all trumps the stigma of being in a lesser Hand can attract more than five personal retainers.
* LittleBitBeastly: Some of the more fortunate half-oni end up looking like this; [[spoiler:Tommy Chang]] can pass as human if he hides his cat ears. Others are closer to full-on PettingZooPeople.
* MagicAIsMagicA
* {{Magitek}}: Melding magic with modern technology is one of Tinker's hobbies. Her hoverbike invention in particular has paid off exceptionally well.
* TheMagocracy: Elven society.
* TheMaze: In her dreams.
* MysteriousParent: [[spoiler:Esme.]]
* NamedAfterSomebodyFamous: Tinker's grandfather loved to do this, naming his children and grandchildren Leonardo Da Vinci Dufae, Ada Lovelace Dufae, Alexander Graham Bell, and Orville John Wright.
* NameThatUnfoldsLikeLotusBlossom: The elves tend to have long, poetic names in this fashion; Tinker's bodyguard, for example, is named Galloping Storm Horse on Wind. Or, for everyday use, "Pony".
* OneWordTitle: Whether you call the series ''Tinker'' or ''Elfhome'', it's one, and both are names of books in the series. Book 1 and three, respectively, with the last book being called ''Harbinger''.
* OurElvesAreBetter: And don't they know it.
* ParentalSubstitute: Oilcan semi-inadvertantly becomes one to a group of elf children in ''Elfhome'', with the twist that - due to how elves age - they're all at least a couple of decades older than him.
* ProtagonistTitle: Tinker, the WrenchWench.
* RescueRomance: Tinker and Windwolf meet via saving each other. Multiple times. Sorting out who owes whom their life leads to complications.
* RoadBlock: Tinker and Oilcan are stopped by a roadblock and asked for papers. [[spoiler:When the men see Windwolf inside, they are ordered to kill them all.]]
* ScarpiaUltimatum
* SecretLegacy: Tinker and her cousin Oilcan.
* SpellBook: The Dufae Codex.
* TactfulTranslation: Elvish being what it was, to English translations often invert this.
* TalkAboutTheWeather: On a first date.
* TextileWorkIsFeminine: Tinker at one point contemplates how wives do laundry.
* TeenGenius: Tinker. Windwolf is also implied to be this in elven terms (he's over 200 years old, but in terms of maturity that's equivalent to about 20 years old in human parlance).
* {{Tengu}}: Lain has a dream where Tinker brings her a Tengu, which she describes as a Japanese elf that is sometimes looks like a crow.
* TrappedInAnotherWorld: The hyperphase gate is destroyed at the end of ''Tinker'', permanently stranding Pittsburgh on Elfhome. This is a problem, because the Westernlands don't have enough resources to support 60,000 humans.
* TwentyMinutesIntoTheFuture: The series is set in 2031, though exact dates aren't given until ''Wood Sprites''.
* UnusualEars: The elves, as expected, have pointy ears [[spoiler:because the Skin Clan engineered it that way, to easily distinguish their slaves. The Skin Clan themselves have rounded ears, allowing them to pass as human.]]
* WillNotTellALie: The elves.
* WrenchWench: Tinker, very much so.
