Nora thought twelve years of marriage meant she knew her husband. Then she discovers Ethan Cole has been cheating on her—and the man who appears at her door is Ethan at twenty, a decade before betrayal turned him into a stranger. He expected a happy future, but learns the woman he adores is preparing to leave him. As the younger Ethan fights to protect Nora from the man he will become, a blood-soaked murder and his absence from every security camera raise one terrifying question: can he change his future, or is it already written?
