Bulletproof — Regan Black

A soldier is nothing without his honor. To avoid a dishonorable end to his decorated military career, John Noble made a deal with the devil. He gave up his name, endured harrowing training, and accepted every mission thrown at him for one purpose: redemption. When he accepts his latest orders, providing personal security for a reporter in trouble, he bargains hard to guarantee it will be his last job for the shadow agency he knows only as Unknown Identities (UI). An ambitious reporter, Amelia Bennett, is about to break the story of her career, if she lives long enough to tell it. Caving to her boss's demand, she hires a bodyguard and soon it is obvious John Noble is the only obstacle standing between her and certain death. Just when John believes he has found someone he can trust and love, who loves him unconditionally for who and what he has become, his orders are amended: Amelia Bennett is to be terminated. Introducing Unknown Identities: an alternative for elite soldiers and spies facing criminal charges... if they can survive the program.
