A fantasy novel by Creator/MercedesLackey, also known as the author of the ''HeraldsOfValdemar'' and ''Literature/ElementalMasters'' series.

[[SwanLake Once upon a time]] there was a princess named Odette who was kidnapped by the evil sorcerer Eric von Rothbart and subjected to an unusual curse -- she is human only at night under moonlight; by day she is a beautiful white swan.

This novel is not about her. This is about the ''other'' swan.

Odile von Rothbart is the dutiful daughter of her father and a rising sorceress in her own right. She keeps his palace without complaint, though she longs for more of her father's approval. Like the Baron, she believes the swan maidens are fickle, faithless creatures who deserve their situation because they have been untrue to their men. But then one day, Odette defies the sorcerer to give her a chance to prove her rehabilitation...

Perhaps the two swans are not so different after all.

Not to be confused with the film ''Film/BlackSwan''.

!!''The Black Swan'' features examples of:
* AbusiveParents: Von Rothbart has been neglecting and undermining his daughter's self esteem for all her life. [[spoiler: He also steals her magic regularly and uses PeoplePuppets magic on her to further his plans. Few people can blame Odile for killing him.]]
** Also, Queen Clothilde has been manipulating her son his whole life so that she can keep the throne, and even intends on having him killed.
* AdaptationalVillainy: Queen Clothilde, and initially Siegfried as well.
* AllMenArePerverts: Yup. From the selfish prince to the priests.
* AnimalMotifs: The swan for Odile, an eagle-owl for Baron von Rothbart, and one of the princesses at the ball is garbed as a hawk.
* AristocratsAreEvil: Baron von Rothbart. Unsurprisingly, Odile herself begs ''not'' to be called "Baroness" at the end.
* ArrangedMarriage: What Odette refused, thus 'earning' her a place in the Baron's flock. Several others are implied to have done the same, including one of the four Little Swans.
* BadDreams: Siegfried has a lot of this after the gypsy girl kills herself. It is never made clear if it is his own conscience acting out or a supernatural element. But given that he first dreams of a lich gypsy girl before learning of her suicide it can be both.
* BetterToDieThanBeKilled: Odette and Siegfried attempt suicide rather than let Von Rothbart separate them. [[spoiler: Odile killing Rothbart and then saving them allows them to have their happy ending.]]
* BigFancyHouse: The Von Rothbart manor is rather luxurious, boasts a very large pond and extensive manicured gardens and also invisible and highly efficient serving spirits, [[spoiler: that are implied to be demonic in nature and bound into servitude by Von Rothbart. They also spy on the inhabitants of the house.]]
* BigFancyCastle: Siegfried's castle is a a few times larger than the large Von Rothbart manor.
* {{Bishonen}}: Siegfried is very handsome, taking after his beautiful mother. Even after he stops actively pursuing women, plenty of them throw themselves at him.
* BodySnatcher: [[spoiler: Von Rothbart uses magic to [[PeoplePuppets take control of Odile]] at the ball so that she can seduce and distract Siegfried -- or at least, not warn him.]]
* [[BoltOfDivineRetribution Bolt of Sorcerous Retribution]]: [[spoiler: This is how von Rothbart puts an end to Clothilde's wickedness. Her fellow plotter Uwe is caught in it but he survives enough to make a full confession and reveal every amoral thing Clothilde has done. Had Clothilde survived she would have been humiliated and lost everything she had worked for.]]
* ChekhovsGun: Odile casually mentions at one point that wizards are generally warded against ordinary weapons but not gold or silver, and that she and her father carries little silver daggers.
* CorruptChurch: Siegfried's priest, upon hearing that he raped a commoner and possibly drove her to suicide, assigns him a trivial penance and broadly hints that she was asking for it. He is replaced near the end of the book by a GoodShepherd.
* CostumePorn: Odile's ballgown. Think PimpedOutDress plus DominoMask plus [[FluffyFashionFeathers black swan wings]] ''plus'' [[GemEncrusted jewels all over]]. Even Odile seems embarrassed at how over-the-top it is.
* CourtlyLove: Discussed between Siegfried, Benno, and Wolfgang. Benno is particularly convinced that high-class women are to be adored but not touched; neither he nor Siegfried hold lower-class girls in such esteem. They get better.
* CryCute: One of the freshly-caught swan maidens at the beginning of the book. Odile's inner monologue is full of acid comments about how [[InelegantBlubbering hideous this would be]] by daylight.
* CurseEscapeClause: If Odette can get a man to swear fidelity to her and remain true for a month, the curse will be broken.
* DancesAndBalls
* DeathEqualsRedemption: Uwe uses his dying breaths to confess to everything he and Queen Clothilde did.
* DoesNotLikeMen: Odile initially.
* DragonWithAnAgenda: Uwe secretly resents Queen Clothilde and has his eyes on the throne for himself. He doesn't get very far with this.
* DrivenToSuicide: The gypsy girl.
* [[TheDutifulSon The Dutiful Daughter]]: Odile to her father; too bad for him he does not appreciate it.
* EverythingsBetterWithPrincesses: Not only Odette, but six other princesses as bridal candidates for Siegfried.
* EvilMatriarch: Clothilde full stop. She plans to kill Siegfried after he produces a heir and a spare so she can keep on ruling.
* ExactWords: Siegfried swears to marry the woman who is standing next to him. Whoops.
* {{Glamour}}: Siegfried sees Odile as Odette at the ball. She is unable to tell him otherwise.
* GodSaveUsFromTheQueen: Clothilde. She wants to murder her son to keep the throne; unusually for this trope, she's otherwise a good ruler. This fits with the theme of the book which brings up the MadonnaWhoreComplex (tastefully at that) and shows that things are never gonna be be that clear cut.
* GoThroughMe: Three different occasions-Odette for the flock, Siegfried for Odette, and (awesomely) the flock for Odette and Siegfried.
* HeelFaceTurn: Both Odile and Siegfried.
* HeelRealization: Siegfried again.
* HeManWomanHater: Von Rothbart. He believes all women (and most men) are naturally faithless.
* HeterosexualLifePartners: Siegfried and Benno, [[spoiler: Odile and Odette in the end.]]
* TheHighQueen: Likely Odette's mother.[[spoiler: Once she becomes married to Siegfried and both are crowned king and queen Odette likely will emulate this.]] On another note, Clothilde presents the world an image of it, but deep down she is anything but.
* HookedUpAfterwards: Broadly hinted for Odile and Benno.
* TheHunter: Von Rothbart.
* InvoluntaryShapeshifting: Odette and the rest of the flock, in contrast with the voluntary shapeshifting of the Baron and Odile.
* IronicHell: Averted for Clothilde, [[spoiler: she gets the real thing, FireAndBrimstoneHell if the religious views shown throughout the book are any indication.]]
* JerkWithAHeartOfGold: Siegfried after quite a bit of character development and a HeelRealization - he later graduates to a truly good guy, after meeting Odette. Benno at times hits this, mostly around Odile, whom he ends up falling for.
* KarmaHoudini: [[spoiler: Arguably Siegfried; yes, he was haunted by guilt and shame for a while, but his victim killed herself, with only his priest knowing, so he gets no punishment (not that he likely would anyway, as a noble.) However, considering that it seems the gypsy girl got to become an ''angel'' and he was redeemed and made a point of becoming a better person, it's justified.]]
* KnightTemplar: How Von Rothbart presents himself, though what he does is really more for his own power's sake than for his cause.
* LadykillerInLove: Siegfried.
* LonelyRichKid: Odile before she starts befriending the swans. Siegfried is a subversion, he has a very good friend in Benno. Double subverted in that no one else really likes him until he shapes up.
* LonersAreFreaks: As Odile starts to spend more time enjoying the company of others and revels in what an incredible pleasure it is she starts to wonder why her father isolates himself from others.
* LoveAtFirstSight: Siegfried for Odette, and Odette quickly follows him. Interestingly, one mostly sees this happening from ''Odile'' aka outsider's view, which actually enhances the heartwarming aspects of it.
* LovePotion: Clothilde used one to marry the King. She contemplates using the same formula on Siegfried or his new bride to keep them infatuated with each other (and thus extend her reign).
* LowerDeckEpisode: This is ''SwanLake'' from Odile's point of view.
* MadScientist: Von Rothbart is a fantasy example, making Odile the MadScientistsBeautifulDaughter.
* MadonnaWhoreComplex: How most men in the story view women, especially Von Rothbart. The finale suggests people are working on fixing this, especially Siegfried due to his character development revolving around him learning respect for women.
* ManipulativeBastard: Von Rothbart, Queen Clothilde, and Uwe.
* MeaningfulName: Siegfried's best friend is called Benno and brings to mind Benvolio from RomeoAndJuliet. Also Odette and Odile are variants of the same name.
* MeetCute: Odile and Benno's first meeting CrossesTheLineTwice into this.
* TheMirrorShowsYourTrueSelf: Von Rothbart has no mirrors in his home because "mirrors show the truth." Used literally on Siegfried in his nightmares; though it was more the mirror shows ''what you can'' '''become''' if you don't shape up NOW.
* MissingMom: Odile has only a father. Losing his wife is hinted to be the Baron's StartOfDarkness.
* MistreatmentInducedBetrayal: Odile and Von Rothbart. Odile admits that she would probably have done anything for him if he'd just asked...but instead he forcibly bespells her to betray her friend, stealing her ''own magic'' to do it, and that's the end of that.
* MoralMyopia: Just about everyone. The sympathetic characters eventually grow out of it as part of their CharacterDevelopment.
* NoWomansLand: While high born women are treated with respect they are still considered pawns and chattel by their fathers. Lower class women on the other hand are constantly disrespected and mistreated. Even Clothilde's scheming is largely prompted by her frustration that she would not be allowed to rule in her own right.
** The finale [[spoiler: with Odile being brought onto the council]] suggests that Seigfried is working on fixing this, if only a little.
* MundaneUtility: Odile frequently uses her magic to make life more comfortable and convenient. The time where she uses magic to clean dirty, dusty tapestries that had not been touched in decades and to make a small island in the middle of a swamp for herself and the flock to use as shelter is particularly awesome. While it might be dismissed as non-threatening kitchen magic by her father, it requires a high level of skill and control.
* OldManMarryingAChild: One of the "little swans" was taken from an arranged marriage to a cruel older man. Later, when she develops a crush on Siegfried's elderly tutor and wants to marry him, everyone thinks it would be a good arrangement. Most likely because he honestly adores her back and they want happy endings for everyone.
* OurLichesAreDifferent: Siegfried seems to think that the gypsy girl has come back from the dead as a lich to torment him even though he ordered that her corpse be staked and buried at a crossroads to prevent such a thing.
* PerspectiveFlip: Of ''Swan Lake''.
* PrincessClassic: Odette, with a touch of RebelliousPrincess.
* ProperLady: Von Rothbart demands it from his daughter. Lady Adelaide in Clothilde's court definitely is one.
* RapeAsDrama: Siegfried, how could you?
** The description can lead one to truly believe Siegfried ''didn't know'' it was actually rape until ''much later''. This leads him to a MyGodWhatHaveIDone moment.
* RegentForLife: Clothilde.
* RequisiteRoyalRegalia: Odette always wears a coronet. As a swan, she wears a crown-shaped pendant.
* RewardedAsATraitorDeserves: The Baron's view of his magical punishments. It doesn't particularly matter to him whether it's real betrayal, treachery which he enticed or tricked the other person into, or just something that is betrayal [[HalfTruth from a certain point of view]].
* {{Scare Em Straight}}: Siegfried's recurring nightmare about the gypsy girl.
* SelfMadeOrphan: [[spoiler:Odile literally stabs Von Rothbart in the back, though he more than has it coming.]]
* ShelteredAristocrat: Siegfried in the beginning is very selfish and self-centered. Mostly because his mother ensured that he would not be fit to rule. Later he starts to become a better person much to the relief of the royal advisers and the others around him.
* ShrinkingViolet: While Odile is quite composed and witty, when she goes to the fete that Clothilde throws she feels very embarrassed and self-conscious because she has grown up in isolation with just her father and the flock as company, and is not used to having so much attention on her. Her over-the-top costume did not help either.
** This is also Von Rothbart's paper-thin excuse to have all the mirrors covered at the fete.
* SilkHidingSteel: Odette, Odile and a few of the princesses (Honoria and Evangeline in particular) that Siegfried is to choose from. In fact Clothilde considers Honoria too strong-willed to make a proper and biddable daughter-in-law. Also Clothilde herself is a darker aspect of it.
* SpannerInTheWorks: The ''gypsy girl''. Just think-if Seigfried ''hadn't'' encountered her, he truly wouldn't have been suitable for Odette...and thus Rothbart would have '''won'''.
* SquishyWizard: {{Averted}} by Von Rothbart, who according to Odile specifically disdains sorcerers who rely on their magic at the expense of mundane strength and combat skill. To that end, he's kept his body quite fit, is very adept with a sword, and has warded himself against most metals used in weapons [[spoiler: although the one he neglects to does him in eventually]].
* StarCrossedLovers: [[spoiler: It's only thanks to Odile's intervention that Siegfried and Odette manage to avert this trope and get their happy ending.]]
* StayInTheKitchen: Von Rothbart's attitude toward his daughter. He is always scornful when Odile attempts to master higher magics but praises her when she applies her magic to domestic pursuits. She is not amused when she realizes this.
* SwansASwimming: Nearly every mention of the flock as swans includes a note about how lovely they are.
* TheScourgeOfGod: Baron von Rothbart, particularly to the swan maidens [[spoiler:and Clothilde]].
* TomboyPrincess: Princess Honoria is an avid and expert hawker and hunter, though [[TomboyWithAGirlyStreak she also keeps up a front of being feminine and proper.]]
* {{Tsundere}}: Odile has dere dere as her default mode, but Benno seems to bring out her tsun side.
* TwiceToldTale
* VampiricDraining: Mages can steal energy from other people to power their spells. Von Rothbart has been doing it to his flock (without their consent) for ''years''.
* TheVonTropeFamily: Baron von Rothbart and his daughter, as in the original story.
* [[WellDoneSonGuy "Well Done, Daughter" Girl]]: Odile, so very much. She could easily have become DaddysLittleVillain except that Baron von Rothbart either 1) didn't think of it or 2) was unwilling to share power.
* TheWisePrince: [[spoiler: By the end of the book Siegfried can be considered this.]]
