The third book of ''Literature/TheSevenwatersTrilogy''. Written by Creator/JulietMarillier.

Fainne, the daughter of Ciaran and Niamh, is sent to Sevenwaters to learn about her family and her heritage. Instead, the outing becomes a moral battle as she struggles with her grandmother’s orders to destroy Johnny, Bran and Liadan’s son and the child of the prophecy. Believing her father to be gravely ill, Fainne performs a multitude of tasks and gathers sufficient information to thwart the FairFolk and their plans.

But even sorcery cannot ease the confusion in her mind, nor can it drive away those to seek to help rid her of the lady Oonagh’s influence. Fainne must make a terrible choice: fulfil the prophecy and risk losing all she holds dear, or fulfil the legacy of the sorceress and risk the future of Erin.

!!This book contains examples of:

* AmbitionIsEvil: Eamonn spent the majority of the trilogy trying to achieve power and influence, just like his father (even though he never knew him). [[spoiler: He redeems himself later by saving Fainne’s life.]]
* AwfulTruth: Oonagh explains that [[spoiler: Johnny cannot become the child of the prophesy because the job requires him to keep watch of the Needle, with no human contact. Johnny is a warrior by nature and isolation would drive him insane.]] Cue Fainne and Ciaran turning the AwfulTruth tables on Oonagh.
* BattleAmongstTheFlames: Fianne conjures RingOfFire to separate Johnny and his opponent from the rest of the crowd.
* BreakTheCutie: In an act of desperation, Oonagh tries to completely break Fainne’s will by [[spoiler: killing Darragh.]] This backfires in the most epic way possible.
* CollateralAngst: Fainne sets a fire in Sevenwaters that [[spoiler: burns Maeve horribly.]] While Fainne feels guilty and shows some remorse, it is nothing compared to the emotional distress the rest of the family is in.
* DeathByDespair: Ciaran thinks that Niamh was DrivenToSuicide because she never recovered from the years of abuse and neglect. [[spoiler: He gets a much better explanation later on from his mother.]]
* FinalBattle: And it’s been a long time comin’, folks.
* FinalSpeech: Oonagh launches into one that, despite a few interruptions, lasts for several pages.
* HeroicBystander: Both [[spoiler: Eamonn and Finbar]] step in to prevent Oonagh from killing more people after watching most of the action. One finds that DeathEqualsRedemption and the other is finally freed of his curse because of it.
* InHarmonyWithNature: This seems to be a theme with magic practitioners, Fainne and Ciaran included.
* IntelligenceEqualsIsolation: Conor is frequently consulted and is considered the most knowledgeable of the Sevenwaters folk. Ciaran is also portrayed as an extremely intelligent man. Both of them live in almost complete isolation from other people.
* ItSucksToBeTheChosenOne: Making sure an entire race of beings doesn’t die out certainly sounds like a drag.
* IWillPunishYourFriendForYourFailure: Oonagh uses this threat against Fainne to the point where it starts to get old. She takes it to the next level during the final battle, just to be a jerk.
* MyGodWhatHaveIDone: After the discover that Oonagh had been duping her, Fainne gets a clear shot of the destruction she’s caused during her journey. Really, it’s laid out in the span of two or three sentences. This realization does not go over well with her.
* OneWomanWail: Foreshadowed multiple times throughout the trilogy. Irish women have apparently mastered the SkywardScream.
* ParentExMachina: Oonagh spends most of the book waiting for Fainne to do something terrible so she can suddenly reappear and gloat.
** Ciaran is an even worse offender. He’s supposed to be a powerful sorcerer and yet he makes no apparent attempt to contact his daughter or help her. He had to have had some idea about what was going on before he randomly appeared [[spoiler: to try and stop his mother’s plans.]]
* SecretKeeper: The child of the prophesy is supposed to live in complete isolation and keep watch over the secrets and lore of the FairFolk.
* SelkiesAndWereseals: Darragh is turned into a selkie by the Fae.
* ShapeShifting: Both Fainne and Oonagh are masters of this. Fainne in particular is a master of the FullBodyDisguise, from altering her appearance to changing herself into animals.
* StalkerWithACrush: Some of the things Darragh does to try and be near Fainne are sweet. Others just raise an eyebrow.
* StreetPerformer: Darragh and the group he travels with are wandering entertainers.
* TheChosenOne: Well, the book is called ''Child of the Prophesy''.
* UnwittingPawn: Fainne.
** Pretty much everyone who comes into contact with Fainne, since Oonagh’s trying to manipulate them all.
* VainSorceress: Dear god, Oonagh couldn’t be more vain if she tried.
