On the day Lieutenant Nate Ryland's baby daughter is kidnapped, he finds hope in the most surprising of allies: Darcy Burkhart, a woman he never thought—never wanted—to see again. But Darcy's son has also been taken and there's nothing that will keep them from bringing their children home. Unfortunately this is no ordinary adversary, and even someone like Nate, who's used to dealing with the worst of society, can't predict the enemy's next move. As the search continues, Nate finds himself admiring the woman he once considered his greatest opponent—and desiring her in a way he never would have thought possible.
