When a small town in Oregon is attacked by a serial killer, Tessa is the only one who can stop him. She is able to absorb the DNA of anyone she touches and reproduce their appearance. As part of an undercover FBI unit, she is sent on a mission to impersonate Madison, a local teenager and the latest victim of a brutal attacker, in order to find the killer before he strikes again. As if pretending to be someone else wasn't hard enough, Alec, the guy who she has been in love for many years, joins her on a mission. The attraction between them only complicates things. Tessa knows she can't let her feelings for Alec get in the way of her case, especially since it's all hopeless. Not only is Alec her self-defense coach, but he also has a girlfriend. Will Tessa find the killer before he kills again? Or will she lose herself in the life she has always longed for?
