With a rock-hard body and steel blue eyes, Mason Decker is about to become the U.S. Marshals' newest recruit. But one last undercover job with a straitlaced attorney will test him to his limits . . . Charlotte Cahill intends to take down an infamous diamond smuggler on the FBI's Most Wanted list-and she intends to do it by the book. That won't be easy with the cocky new temporary deputy on her task force. Mason Decker feels like trouble, especially when his cool gaze wanders across her hot body . . . After his time as a Customs officer, Decker has enough experience hanging out with criminals to know that working undercover means following your instincts, not the rules. It doesn't take long for him to lock horns with Cahill. But when the sexy assistant U.S. attorney is accidentally dragged out of her orderly world and into the turn-on-a-dime tension of Decker's deceptive games, she'll find that nothing is as seductive as playing a new role . . .
