Vampires. They hunt in every major city, hidden by the crowds, shielded by disbelief. They are Killers, and their prey is human. But not all vampires are Killers. The Guardians of the Night sacrifice the superior physical and psychic strength that comes with feeding on humans to protect them. But the Guardians walk a thin line, for even a single kill could leave them helplessly addicted to murder. Jules Gerard has vowed that he will never become a Killer. But when he discovers that the man who turned him into a vampire is dead and kicking in Baltimore, the allure of extra power is tempting. Standing in his way is a human, spitfire Hannah Moore, who has followed him to Baltimore to help him confront his past. Hannah doesn't seem to realize how dangerous vampires can be-and despite his facade of disdain, Jules has a real soft spot for the petite PI. Jules is going to have to choose: Vengeance or love? Damnation or redemption?
