A notorious female assassin brings trouble straight to Ryker's doorstep, in this new thriller from the bestselling author of Protector . . .

James Ryker knows the ghosts of his dark and violent past are never far away. Yet he's still taken aback when he sees Leia Devereaux's face at his door. Even more surprising is that the woman he knows to be a lethal assassin claims she's not there to hurt him, but to ask for his help in keeping the stranger accompanying her, David Muller, alive.

She says Muller is more valuable than Ryker can imagine. But Ryker isn't given any time to investigate before chaos descends upon them. In the aftermath, Devereaux disappears and Ryker is left with only questions.

Why would the deadly Leia Devereaux come to Ryker for help? What did the notorious assassin want with David Muller? Most importantly, who are the armed assailants now out for Ryker's blood?

To find the answers, Ryker has only one choice: To do what he does best. Fight back . . .
