Uncontrollable by Nina Croft

Quinn Sutherland, second in command of the Tribe, a group of powerful telepaths, has always been certain of who and what he is — one of the good guys. All he wants is to keep his friends safe — no easy feat when everyone in the world is after them. While on a rescue mission, he meets a mysterious FBI agent, who appears to know a lot about them, and seems to want the same thing he does. But her assignment could literally mean the death of him…

Only when she’s sent back to the twenty-first century to eliminate a group of rogue time travelers, she never guesses she’ll fall for a man who died two thousand years ago… Quinn awakens emotions she hadn’t known existed, and for the first time, her loyalties are tested.
