A brand-new seductive thriller from #1 New York Times bestselling author of The Housemaid! She only kills bad men. At least, that's what she believes. . . Samantha sleepwalks. Ever since she was traumatized by a cruel incident as a teenager, she's woken up with raw, bleeding fingertips, unexplained bruises, and memory gaps. But after twenty years, she has learned how to control it. By day, Samantha is a nurse. By night, she has a deadly secret: when she kills, the sleepwalking stops and her nights grow quiet. Her victims are predators, abusers, men who deserve it. Or so she tells herself. But when bodies begin to surface that she doesn't remember killing, and a darkly charming stranger enters her life, Sam is forced to confront a terrifying possibility: what if the most dangerous thing about her isn't what she does awake - but what she does while asleep? Dark, twist-packed, and impossible to put down, The Sleepwalker is a psychological thriller about secrets, obsession, and how far we'll go to justify our darkest desires.
