At DeRose & Associates Private Investigators in Virginia, Angie DeRose strives to find and rescue endangered runaways. In the wake of her mother's sudden death, Angie makes a life-altering discovery: in her parents' attic is a photograph of a little girl, with a code and a hand-written message on the back: "May God forgive me." Bryce Taggart, the US Marshal working with her agency, agrees to help Angie learn the fate of the girl in the photograph. But the lies they unearth mean everything she cherishes will be threatened by the repercussions of one long-ago choice-- and an enemy who will kill to keep a secret hidden forever.
