An ordinary snapshot causes a mother’s world to unravel in #1 New York Times bestselling author Harlan Coben’s shocking thriller. When Grace Lawson picks up a newly developed set of family photographs, there is a picture that doesn't belong - a photo from at least twenty years ago with a man in it who looks strikingly like her husband, Jack. And though Jack denies it's him, he disappears that night, taking the photo with him. Now, to save her family from a fierce, silent killer who will stop at nothing to get the photo, Grace must confront the dark corners of her own tragic past... “Harlan Coben remains one of the best in the game...It’s one of those books in which the main character—and readers—have no real idea what’s going on until the very last pages. This is both highly satisfying and enjoyably frustrating, especially when the plot twists are being carefully doled out by a pro like Coben.”—The San Francisco Chronicle “It’s only when the last page turns that the reader has a chance to breathe, say ‘Wow!’ and marvel at the impressively interconnected structure.”—The Miami Herald
