For a devoted wife and mother, a restful getaway descends into an inescapable nightmare in a novel of dark psychological suspense by the author of The Body Next Door . Harlow has almost everything she ever wanted: a passionate marriage, an adorable stepson, and a fresh start at her husband Gregor's boyhood home on the water. If only she could get pregnant, her happiness would be complete. But soon after they arrive on the misty, tree-cloaked island, Gregor starts to change--and Harlow is shaken by his odd connection to their neighbor Kirsten, a luminous tradwife influencer. Then, deep in a wooded ravine, Harlow finds evidence of an unspeakable murder--or thinks she does. Desperate to know what's real and what's only in her mind, she tracks down rumors of missing girls and bloody rituals, and begins to suspect that her marriage, too, hides a menace she never saw coming. Each day the feeling grows: the safest thing she can do is run . But from what, Harlow can't even begin to imagine.
