Dark secrets and painful memories resurface in this thriller by bestselling author Harlan Coben. When Grace Lawson picks up a recently developed set of photographs, she is surprised to find a photo of her husband from 20 years ago in the set. But that is nothing to her husbands reaction when he sees the photo: he promptly vanishes. As Grace embarks upon an increasingly dangerous search for her husband, she is also forced to confront a traumatic event from her own past--a riot at a rock concert that left her with a limp.
