In this electrifying novel of suspense, #1 New York Times bestselling author Iris Johansen takes us deep below the surface, where a ruthless killer strikes without warning, without mercy—and with the deadliest intent.   Marine researcher Melis Nemid is treading dangerous water—and she’s about to be dragged under. Melis knows something that has already caused one oceanographer to disappear from the face of the earth . . . and that’s only part of a past torn by violence and betrayal. She thought she had put that past behind her when she arrived at her Caribbean island home to research dolphin behavior.   But Melis’s peace—and her life—are about to be shattered by a savage killer who is cutting a path of destruction and death that leads directly to her. Only one person can save her—a man who claims to be a fellow oceanographer. But what this enigmatic stranger really wants, Melis may not discover until it’s too late. Because whoever is after her knows her fears intimately. And soon Melis will be forced to relive them all over again. Except for the final nightmare—the one she cannot possibly survive. Read Less
