''Wolves of Mercy Falls'' is a book trilogy written by Maggie Stiefvater which takes place in Mercy Falls, Minnesota.

At the start of ''Shiver'', Grace is bitten by the wolves that live behind her house, but she is saved by a different wolf with mysterious yellow eyes. After that incident, Grace becomes obsessed with the wolves; more specifically, her yellow-eyed wolf.

The yellow-eyed wolf, however, lives a double life. During the winter, he is an animal wandering through the forest, but when summer arrives, Sam and all the other wolves behind Grace's house turn human.

The second book, ''Linger'', was published in July 2010. The conclusion, ''Forever'', was released in July 2011. A fourth entry in the series ''Sinner,'' a continuation focusing on Cole and Isabel will be released later on in 2014.

!!Tropes used in this series:

* AbusiveParents: ''All of them''. Sam's parents take the cake, but Grace's should've been put away for neglect long ago. Also Shelby's parents, and possibly the Culpepers as well.
* AlphaBitch: Isabel starts off as this.
* AmbitionIsEvil: Shelby
* AscendedExtra: Isabel and Cole went from being supporting protagonists to getting an entire book focusing on them.
* BrilliantButLazy: Cole
* CallingTheOldManOut: Grace does this to her parents [[OnceASeason Once A Book]].
* ChekhovsGunman: Officer Koening
* DeusExMachina / ContrivedCoincidence: So, wait, our [[HeelFaceTurn new ally]] [[spoiler: Officer Koenig]] just ''happens'' to have [[spoiler: inherited a tract of land which is absolutely ''perfect'' for relocating the pack?]] Really?
* DiabolusExMachina: In an unusual form: [[spoiler: a deer]].
* DownerEnding: The end of ''Linger'' [[spoiler: undoes ''everything'' the protagonists tried to accomplish in ''Shiver'', only mixing it up by having Grace turn into the wolf.]]
* [[DroppedABridgeOnHim Dropped A Bridge On Her]]: The girl Shelby kills in the opening of ''Forever''? [[spoiler: Olivia, absent since the end of ''Shiver''. We don't find out it's her until later.]]
* [[spoiler: EarnYourHappyEnding]]
* FakeOutMakeOut: Cole and Isabel in ''Forever''.
* ForeShadowing: While Grace is buying a new car [[spoiler: Sam jokes to Grace that if the car "hit a deer it would just hiccup and keep going." but much later the car does in fact hit a deer and breaks down. To make matters worse, without the car heater keeping Sam warm, he finally shifts permanently into a wolf but not before tearfully saying goodbye to Grace and Beck.]]
* FollowTheLeader: Then again, it does help the surge of human/non-human romance craze started by ''Twilight''.
* FoodPorn: The description of the candy shop in ''Shiver'' may make you drool.
* FreudianExcuse: Shelby has one.
** This is deconstructed somewhat. Although readers are told that Shelby's past life was appalling (and heck, it must have been to create someone so spectacularly fucked-up) her backstory is never used to justify her AxCrazy deeds.
* FullyEmbracedFiend : Shelby. And Cole to a lesser extent
* GenkiGirl: Grace's friend Rachel.
* HandsOffParenting: Grace's parents. Her mom cares more about her art than her daughter essentially. In ''Forever'', she claims this is because [[FreudianExcuse her parents made her life miserable]] [[MyBelovedSmother by never letting her do anything she wanted.]]
* HeroicSacrifice: [[spoiler: Cole towards the end of ''Forever'' injects himself with his personally created serum shifting himself into his wolf form so that he may fight off Shelby giving Sam enough time to escape and lead the pack to safety from the aerial hunt, causing himself to end up getting shot after killing Shelby. He manages to survive though. Just barely]]
* IAmTheBand: Cole St. Clair in relation to NARKOTIKA. He's the one who jumps out on album covers, and he's most likely the one who leads his friends Jeremy and Victor into temptation.
* IChooseToStay: At the end of ''Shiver'', [[spoiler: Olivia]] chooses to try and live with lycanthropy rather than gamble on an incredibly risky cure.
* IJustWantToBeNormal: Many of the werewolves feel this way.
* ImportantHaircut: Isabel gets one in ''Linger''.
* InterSpeciesRomance: Sam and Grace.
* InsufferableGenius: Isabel
* InvoluntaryShapeshifting: The werewolves. Shifting all depends on the temperature. How cold it needs to be for a werewolf to shift from human to wolf depends.
* JerkWithAHeartOfGold: Isabel and Cole
* KarmaHoudini: Shelby [[spoiler: gets away alive despite trying to MurderTheHypotenuse in ''Shiver''.]]
** [[spoiler: She gets what she's got coming in ''Forever'', though.]]
* KillItWithFire: Technically speaking. [[spoiler: The 'cure' for the wolves is to inject them with meningitis, which they describe as 'burning out the wolf inside']]
* LastNameBasis: Beck.
* LoveAtFirstSight: Grace and Sam.
* LoveMakesYouEvil: Shelby.
* LoveTriangle: A small one with Grace/Sam/Shelby. [[LoveDodecahedron Grace/Sam/Isabel and Cole/Isabel/Sam]] are both teased -- most overtly with an IndirectKiss between Sam and Isabel at the beginning of ''Linger'' -- but [[AbortedArc neither goes anywhere.]]
* MadScientist: Cole in ''Forever'', extending to [[spoiler: making himself a guinea pig for his own experiments.]]
* MoralityPet: Inverted. In the first book, Isabel has a yappy little dog, appropriate to her RichBitch status. Shortly after [[spoiler: Jack]] kills the dog, she does a HeelFaceTurn for unrelated reasons.
* NakedFirstImpression: Isabel and Cole in ''Linger''
* NiceJobBreakingItHero: At the end of ''Linger'', it turns out [[spoiler: lycanthropy is actually the body's (super)natural defense mechanism against a toxin- spread by the bites- that kills the victim slowly. "Curing" the shifts merely causes the toxin to kill the victim ''faster''.]]
** Annoyingly, this plotline is then ''[[AbortedArc dropped]]'' in the third book, in favor of a CliffhangerCopOut: [[spoiler: the meningitis cure from ''Shiver'' works, but simple heat stroke -- which supposedly killed Grace's lycanthropy -- just leaves the body defenseless.]] Or something like that. Honestly, you get the feeling that [[NewRulesAsThePlotDemands Stiefvater's not too clear on how it all works, either.]]
* OurWerewolvesAreDifferent: Very different indeed.
* [[ProudWarriorRaceGuy Proud Warrior Race Girl]]: Shelby feels this way about being a wolf.
* ReTool: WordOfGod says that the third book was finished, then ''completely rewritten from scratch'' because [[DoingItForTheArt the author wasn't happy with it.]] Some problems resulted, possibly including the above mentioned CliffhangerCopOut.
* RichBitch: Isabel. Until she gets CharacterDevelopment, anyway.
* ShadowArchetype: Cole to Sam, as TheLancer sub-type.
* SingleTargetSexuality: Sam and Grace only have eyes for eachother.
* StalkerWithACrush: Sam, even if he was a wolf at the time, and Shelby gets like this with Sam, too.
* SummonBiggerFish: The theorized cure for lycanthropy? [[spoiler: Bacterial meningitis.]] [[DangerousForbiddenTechnique Results may vary]].
* SupernaturalGoldEyes: Sam in both human and wolf form.
* TechnicolorEyes: Sam's eyes are naturally yellow.
* TheirFirstTime: Sam and Grace in ''Shiver''
* {{Tsundere}}: Isabel. She's almost always in tsun-mode but she does have her occasional dere moments,
* WhatHappenedToTheMouse: In ''Shiver'', Three teenagers [[spoiler: are infected with lycanthropy by Beck]]. One turns out to be [[EarlyBirdCameo Cole]], the second his friend Victor, but the third never shows up again.
** In ''Forever'', chapter fifty-eight: Did [[spoiler: Isabel ask Cole in?]]
* WhatTheHellHero: Isabel to Sam in ''Linger'', for [[spoiler: ignoring the fact that Grace is ''dying'' so as not to ruin their "Dream life."]]
** And again in ''Forever'', for ''still'' not doing anything about it [[spoiler: even after Grace turns wolf.]] Sam can be a real EmoTeen sometimes...
* WrongGenreSavvy: Rachel displays this in Forever, refusing to come near Sam (who is a suspected murderer), and basically displaying more sense than any girl in a horror movie ever has...too bad she's in a teen romance book, and not the next Friday the 13th
