Tess thought her life would settle after the death of her husband, Ballard Crafton. After all she'd escaped Russia with the formula to his secret serum that transforms ordinary soldiers into unstoppable machines. She was certain the Russians thought Ballard's notes were lost in the explosion that destroyed his lab, but one man believes that Tess possesses the precious information, and he wants it for his own wicked agenda. Hired assailants dog her night and day. She needs help and she needed it weeks ago. Now she turns to First Force for protection only to find the team is away with only one operative at First Force headquarters holding down the fort-Dan Garrison. How can Dan keep her safe when he isn't sure that he believes her story? How can Tess gain his trust, and how can either of them deny the underlying passion that is exploding between the fine line of deception and danger?
