Elena Whitmore is taken from the human world into Valeria, a realm ruled by ancient laws and immortal courts, where her life is forfeit the moment she crosses its borders. To survive, she strikes a bargain with Dorian Hale, a powerful vampire bound by restraint and reputation: in exchange for her life, she will become his living source of blood, bound to him alone. What begins as a transaction rooted in survival slowly shifts as Elena adapts to Valeria—and as Dorian finds his carefully maintained control unraveling in her presence. As desire, power, and choice blur, both must confront whether the bargain was ever truly about blood, or about something far more dangerous.
