Vayl is the CIA's top assassin. A master of black ops, he has never failed. He's also a 291-year-old vampire. Assigned to protect Vayl, if such a formidable creature can be said to require protection, is Jasmine Parks - 'Jaz' to her friends. But Jaz has got problems - and not just the run-of-the-mill ones you'd expect from someone whose job consists of putting her life on the line for an undead assassin. She hasn’t had sex in god knows how long, so Vayl's almost overpowering vampire charisma is making it increasingly difficult for her to keep their relationship . . . professional. Her personal life is a long line of missed birthdays and Christmases, and lies and excuses to her family. And then there's that other thing: the blackouts. See, there's times that Jaz can't account for and things that happen in those times that Vayl - not to mention the CIA - may not appreciate. And if they find out, Jasmine knows it won't just be her contract that's terminated . . .
