After a lifetime of constant danger as an assassin, Ivy is finally safe to step out of the shadows. She's even considering allowing a man into her life-a sexy former intelligence agent who makes her want more than she's ever dared hope for. Except he doesn't know the truth about her past-or what she's done. She owes him and wants to wipe her slate clean once and for all. But when a past threat suddenly resurfaces, it puts countless lives at stake and threatens to destroy everything she's built.

No one is safe.

Walker has zero regrets about leaving his intelligence career years ago to take care of his family, but a recent terrorist attack at home thrusts him back into the action. Now recent bombings in the UK all point to one of his former assets-who was supposed to be long dead. Once again he finds himself teamed up with Ivy, the unforgettable and mysterious operative he's undeniably attracted to. She awakens something inside him he thought was gone forever. But as hot as the unexpected fire burns between them, he knows she's holding something back. Something big. Even so, he has no choice except to trust her-because they're running out of time to stop a madman bent on exacting vengeance. And this time, it's personal.
