In a dangerous world where Hell rules the night, one girl discovers the true cost of survival. Spending years on the run from the demon who murdered her parents, seventeen-year-old Cami Anders relies on a rogue demon hunter to keep her safe. Despite the threat of Hell on earth the night brings, Cami manages to live a normal life, learning what she can from her guardian about the world she fears. The arrival of a mysterious boy pulls Cami deeper into the realm of demons, unveiling secrets about her life that her guardian had kept from her. She discovers the truth about her parents and the real reason she’s been on the run, a lifestyle she wants desperately to change. With help from new allies—a sassy young hunter fresh from the Hunter’s Academy and a hot, strangely familiar half demon—Cami takes charge of her life and learns to fight back instead of fleeing. But when the demon from Cami’s past arrives to collect her soul, which he believes is rightfully his, she is given an impossible ultimatum. Cami must decide what’s more important—sacrificing herself for those who would die to protect her or saving her soul, her most costly possession.
