In the modern dark-night society of Europe and America, werewolf royalty defines honor by bloodline, and vampire nobles control wealth through contracts. The half-blood girl, Lia, carries her mother's human surname, Walker, but has no werewolf family name, making her look useless to both clans. At the Blood Moon banquet, she’s humiliated, expelled, and injured, yet an ancient prophecy singles her out in a vision. From the ruins, she uncovers her first piece of evidence and steps into the more dangerous vampire territory, inching closer to her true origins.
