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--with nothing to rely on but Malorie's wits and the children's trained ears. One wrong choice and they will die. And something is following them. But is it man, animal, or monster?
