Detective Elise Sutton is drawn to cold cases. Each crime is a puzzle to solve, pulled from the past. Elise looks for cracks in the surface and has become an expert on how murderers slip up and give themselves away. She has dedicated her life to creating a sense of order, at work with her ex-marine partner; at home with her husband and two young daughters; and within, battling her own demons.

Elise has everything under control. Until one afternoon, when she walks into a department store and is forced to make a terrible choice: to save one life, she will have to take another.

Steeped in guilt, and on a leave of absence from work, she's numb, even to her husband and daughters, until she connects with Wade Austin, the tall man whose life she saved. But Elise soon realizes that he isn't who he says he is. In fact, Wade Austin isn't even his real name.
