Since turning sixteen, Lila's life is plagued by terrible headaches, nose bleeds, hallucinations, and white light shooting from her palms. She begins to seriously doubt her sanity until she discovers the truth—all of her new-found ailments are inherited from her father, a demon. But Lila's daddy issues don't end here; her demon-daddy is hell-bent on sacrificing her in order to open the town's legendary Gate of Hell. As if this realization isn't devastating enough, couple it with the fact that her faithful boyfriend, Liam, is actually an Atoning Angel trying to earn his way back to Heaven. Unfortunately, Heaven doesn't smile upon Atoning Angels having love lives, especially with daughters of the enemy.
