Vampire Police Captain Jess Vandermire is hunting a serial killer vampire. The trouble is, Jess is experiencing blackouts, and every time she does, another woman turns up dead. Has she slipped over the dangerous slope into full vampirism? Is she the serial killer she's hunting?

Lieutenant John Brittain makes it his job to find the killer and prove Jess innocent, but it's hard to be human in a world of super-strong, super-fast vampires. His best weapon is his tough-cop intellect and he's using it for all he's worth. Yes, Jess is a vampire, and yes, she's capable of killing. He knows, however, that she hasn't committed these crimes, and he has the horrible feeling that if he doesn't catch the killer soon Jess will be the final victim.

As Jess and Britt wage war against this evil vampire, it becomes a battle for the last vestiges of Jess's own humanity. Soon the question becomes, who will draw first blood?
