One moment of weakened vigilance risks everything—and love is the biggest price of all.

Raine, an ex-Guardianship guard who's lived for centuries, is cursed to take pleasure from others in order to survive. She dares not use someone more than once for fear of killing them. It's easy to keep everyone at arm's length when she's already hiding from corrupt members of the agency she worked for.

When Brian, the ruggedly handsome maintenance man at Ferraro's Club uncovers secrets from the very same people she's running from, Raine battles with her conscience. Protecting him exposes her, but she can't just stand idly by while they decimate him.

Now, Raine's worst fears might come true. Every day that passes brings them closer together, and their attraction may topple every barrier she's ever built around her lethal allure. Her unchecked desire for him risks his life—but leaving him might risk hers.
