Back in 1997, well before the world got its hands on ''Literature/{{Twilight}}'', supernatural romances for teens were not really the biggest genre out there. One of the more notable of the titles was ''Blood and Chocolate'' by Annette Curtis Klause, who also wrote a [[Literature/TheSilverKiss vampire novel]] before this one.

The novel revolved around 16-year-old Vivian Gandillon, pretty much a normal high school outsider... who happens to be a werewolf. Though her family once lived in a secluded town where they could all be themselves, they were forced to flee in exile when one of their pack accidentally murdered a human. It is the only rule they hold sacred, the rule that protects them from discovery and extinction. So now they are scattered across a small town, mingling with humanity. Vivian also lost her father in the move, and struggles to hold herself and her mother together.

For the first time, she attends a normal school, and there she meets a human boy, Aiden. He is quirky, an outsider like her. And she finds his kindness a refreshing change of pace from her squabbling pack mates. Her family of werewolves is leaderless with her father dead, and the battle for succession is fearsome. Vivian finds herself unwittingly drawn into the center of the leadership quarrel, and in the sights of a werewolf who would like to call her his own.

Torn between the human world and that of the pack, Vivian struggles to find herself and where she belongs. What does she want more, blood or chocolate?

There was a film version released in theaters in 2007 that is unfortunately InNameOnly. Not related to the Music/ElvisCostello album of the same name.

* ArrangedMarriage: Of a sort. The female werewolf who wins the 'Bitches Dance' (a NoHoldsBarredBeatdown) becomes the new Alpha's mate. Most female werewolves knowingly enter the fight in the hopes of becoming the Alpha's mate; however [[spoiler: Vivian accidentally wins the fight when she unthinkingly steps in to protect her mother from Astrid. To her horror, she is announced to be Gabriel's (the new pack leader) mate]]. In the end [[spoiler: Vivian falls for Gabriel and [[PerfectlyArrangedMarriage happily accepts becoming his mate]]]].
* BettyAndVeronica: Aiden and Gabriel, respectively, for Vivian.
** [[spoiler: Actually a case of BettyAndVeronicaSwitch when Aiden's racism comes into play.]]
* ComingOfAgeStory: A major theme/plot point is Vivian learning to come to terms with her dual nature and finding out who she truly is.
* DaddysGirl: Vivian
* DerailingLoveInterests: [[spoiler:Aiden]].
* DrivenToSuicide: [[spoiler: Vivian]] briefly intends to kill herself due to [[spoiler: believing she had killed several humans]]. Luckily, the truth behind [[spoiler: the murders and the real culprit]] comes out before she can go through with it.
* EyeScream: During the Bitch's Dance, [[spoiler: Vivian]] tears out one of [[spoiler: Astrid's]] eyes.
* FrameUp: [[spoiler: Rafe and Astrid try to frame Vivian for killing several humans]].
* HuntingTheMostDangerousGame: More pointedly present in the movie, as it becomes ''tradition'' instead of a forbidden practice.
* InNameOnly: The film adaptation has nothing to do with the novel, save for werewolves, some of the characters' names and the title (which doesn't even make sense anymore because of how much they changed the film's ending from the book).
* InterspeciesRomance: Between Aiden, a human, and Vivian, a werewolf. [[spoiler: It's hinted and eventually confirmed that Gabriel was once in a relationship with a human girl, which ended very badly]].
* LiteraryAllusionTitle: To Steppenwolf.
* TheLostLenore: [[spoiler: Gabriel's human girlfriend. He [[AccidentalMurder accidentally killed her]] after inadvertently transforming in front of her, causing them both to panic]].
* LoveDodecahedron: Vivian wrestles with her affection for Aiden and her growing appreciation for Gabriel; meanwhile, her childhood friend Rafe is in love with her, but willing to settle for the crazy and reckless Astrid, who has her sights on Gabriel so she can be the new alpha's consort.
* MeaningfulName: Vivian means "lively". In addition to the obvious, [[Literature/TheSilverKiss another female protagonist's name means "(eternal) life"...]]
** Vivian’s surname, Gandillon, refers to a historical case of a French family accused of and executed for lycanthropy in the 1500s. Considering that Vivian’s family has French roots and were said to have fled to America during a period of “werewolf hysteria,” it’s entirely possible the author intended to imply the survivors were her ancestors.
* MoreDeadlyThanTheMale: Alpha fights: widely announced, pretty standard dominance fare. Alpha mate fights: no warning, no challenge, straight to NoHoldsBarredBeatdown.
** Notably, males must be at least twenty one years of age to engage in the Ordeal. Females, on the other hand, only need to be sixteen...
* MuggleAndMagicalLoveTriangle: Vivian has to choose between Gabriel (werewolf) and Aiden (human). [[spoiler: In the end she chooses [[LastGuyWins Gabriel]]...partly because Aiden freaked out and tried to kill her when he learned she's a werewolf]].
* MurderTheHypotenuse: [[spoiler: Rafe hopes to kill Aiden, though whether it's because he wants Vivian or because his [[LoveMakesYouEvil relationship with Astrid]] has driven him to it is left unclear.]]
* NeckSnap: [[spoiler: How Gavriel kills Astrid as punishment for her crimes in the end]].
* NoGuyWantsAnAmazon: Averted with Aiden, who admires Vivian and even calls her an Amazon. It never comes up with Gabriel.
* NonHumanLoverReveal: Vivian eventually reveals her true form to Aiden.[[spoiler: He doesn't take it well]].
* OurWerewolvesAreDifferent: The werewolves of the novel are their own species, separate from humanity. They call themselves ''homo lupus''. The mystics in the pack believe they are children of a moon goddess, while the more scientific-minded believe they split from humanity millions of years ago, perhaps evolving from a mutant strain of small mammals.
** InvoluntaryShapeshifting: The full moon forces them to transform into their wolf form, whether they want to or not...
** VoluntaryShapeShifting: ...But otherwise, they can change forms at will.
* ThePowerOfLove: [[spoiler:A kiss from Gabriel is what it takes to break Vivian's ShapeShifterModeLock.]]
* ShapeShifterModeLock: [[spoiler:Towards the end of the book, Vivian gets stuck halfway between wolf and human form, a symbol of her still feeling stuck between her human and werewolf sides.]]
* ShipSinking: [[spoiler: The Aiden and Vivian ship. Trying to murder your girlfriend simply for being a werewolf, even after she tried to protect you, tends to do that]].
* SilverBullet: [[spoiler:Aiden melts down a pentacle necklace into silver bullets to kill Vivian after he discovers her secret.]]
* TookALevelInJerkass: [[spoiler: Aiden after learning the truth about his girlfriend, culminating in him attempting to murder her]].
* UnluckyChildhoodFriend: Rafe at least sees himself like this.
* VanHelsingHateCrimes: [[spoiler: Aiden tries to kill Vivian after learning she's a werewolf, viewing her as dangerous and evil. In fairness, both he and initially Vivian herself had believed she was responsible for killing several humans, though Aiden barely even gives Vivian a chance to explain the truth]].
