Welcome to a mesmerizing world where vampires hide among humans. This centuries-old species has its own rules, code of conduct, and taboos. Only the FBI knows that vampires exist—and although the Bureau agrees to keep their secret, it also plots to give humans the upper hand.

Turning mortals into vampires is forbidden.

But there are creatures who refuse to play by the rules.
 
Ever since he was turned, FBI special agent Ty Duncan has had one mission: bring rogue vampires to justice. As a recruiter for Belladonna, a shadow agency formed to keep vampires in check, Ty must tap Ana Martin, a troubled ex–gang member and one of the few mortals who can infiltrate places that his kind and the law cannot. From their first encounter, Ty fights a hunger to make Ana his own.

When Ty claims to have information about Ana’s missing sister, Ana has no choice but to trust this captivating stranger who awakens her deepest desires. But as she and Ty climb the heights of pleasure and passion, an enemy is conspiring to destroy them both.

Can Ana help Ty find his humanity in a love that could heal them both, or will their passion lead them into a darkness impossible to escape?
