Pureblood werewolf heir Claire is betrayed by her best friend Sophia and vampire descendant Lucas in her past life, burned alive at the blood moon sacrifice. Reborn after enrolling in Mystic Falls High, she seeks Elijah, a vampire progenitor sealed for a century. She frees him with her ancient bloodline and signs a vengeance pact. Hiding their identities at school, they outwit foes, recruit local werewolf Tyler and uncover the scheme to unlock primal seals with pureblood power. When the blood moon rises again, Claire and Elijah defeat Lucas and Sophia, end the town’s supernatural peril, and turn from contract allies into soulmates.
