Something is out there . . . Something terrifying that must not be seen. One glimpse and a person is driven to deadly violence. No one knows what it is or where it came from. Five years after it began, a handful of scattered survivors remain, including Malorie and her two young children. Living in an abandoned house near the river, Malorie has long dreamed of fleeing to a place where her family might be safe. But the journey ahead will be terrifying: twenty miles downriver in a rowboat—blindfolded. One wrong choice and they will die. And something is following them. But is it man, animal, or monster? Engulfed in darkness, surrounded by sounds both familiar and frightening, Malorie embarks on a harrowing odyssey—a trip that takes her into an unseen world and back into the past, to the companions who once saved her. Interweaving past and present, Josh Malerman's breathtaking debut is a horrific and gripping snapshot of a world unraveled that will have you racing to the final page.
