In a world where vampires are known but strictly segregated from humans, Sienna Vale, a brilliant but jaded trauma psychologist, is assigned to a controversial new program: helping rehabilitate emotionally unstable vampires who’ve broken the code of conduct—feeding without consent. Her first patient is Lucien Thorne, a centuries-old vampire once revered as a warrior prince, now kept in high-security isolation after a string of violent feeding incidents. Rumors swirl that he used to dominate entire cities—not just in battle, but in bed. Sienna enters the job believing she can’t be seduced by any monster—until she meets him. Lucien is dominant, dangerously intelligent, and shockingly perceptive. Their sessions become a game of psychological seduction, with him slowly unraveling her carefully controlled life. When Sienna discovers that vampires aren’t born—but made through ritualistic submission and pleasure—she’s dragged into a world of dark ceremonies, ancient secrets, and blood-fueled desires. As the boundary between doctor and patient shatters, so do the rules—leading to a bond forged in lust, pain, and deep emotional hunger. But Lucien has enemies who will kill to prevent his release… and they’re watching Sienna.
