Dive into the next thrilling stand-alone novel in New York Times bestselling author Dianne Duvall's "fast-paced and humorous" (Publishers Weekly), "utterly addictive" (RT Book Reviews) Immortal Guardians series.

Immortal Guardians have hunted and slain psychotic vampires for thousands of years. Now someone is hunting them. Humanity remains oblivious to the existence of immortals, vampires, and gifted ones, so how does this rising nemesis even know who they are and where to find them? Could it be the machinations of an old nemesis-one they thought they defeated? Or is this something new? Because unlike the foes they've faced in the past, this one doesn't just target immortals. He targets those who are near and dear to them.

A gifted one under the Immortal Guardians' protection, Nicole has worked hard to land her dream job-that of an Immortal Guardian's Second or mortal guard-and loves working with Sean. He's smart. He's funny. And despite the sometimes dark existence he leads, the two of them laugh a lot. Years spent as a special ops soldier prepared Nicole well, enabling her to keep Sean safe despite his tendency to dive headlong into danger. But can it keep her safe? The enemy they face is determined and shrewd. Uncovering his identity may require new methods of engagement and force her to take a few risks.

Sean hasn't been immortal long, but he knows the rules. And according to the rules, Nicole is off-limits. She's his Second. His guard. His best friend. The one person who knows him better than anyone else. Though he loves every minute he spends with her, friendship is all they can ever have... isn't it? Sean soon begins to question that as the two of them engage in a deadly cat-and-mouse game with the enemy, one that will reveal the true depth of their feelings for each other and drive him to abandon the rules altogether.
