A wife’s search for her husband’s true identity spirals into a nightmare of fear and paranoia in a twisting novel of psychological suspense by the Edgar Award–winning author of Or Else.

Only ten days into their marriage, Imogen and Lev Carmichael are on a honeymoon cruise in the Mediterranean when Imogen suspects her husband of being unfaithful. Amid the recriminations, denials, and rage, Lev falls overboard into the water. It’s a miracle he’s found alive. And with no memory of what pushed him—and Imogen—over the edge.

Back home among family and friends, Imogen and Lev are finally starting to readjust. As terrified as Imogen is of Lev’s memories returning, it’s her suspicions of infidelity that get the best of her. Then, searching for clues, she discovers a woman from Lev’s past he never told her about…a woman who has been missing for years. More alarming is that Imogen soon has reason to believe that Lev remembers more than he’s letting on. But why would he lie?

The man Imogen loved, married, and trusted is a man she’s now beginning to fear. And she must decide how far she’s willing to go to uncover the truth.
