As the town suffers a mysterious death, more kids disappear and the boys experience a series of unsettling phenomena; it becomes clear that the fate of their missing classmate, Margo Combs, pales in comparison to what lies in wait in the margins of the town.
Between avoiding the bullies who are stalking them, and running from the encroaching lethal darkness, the walls are closing in around Brooks and his friends. They soon realize their fates are inextricably bound, and if they have any hope of surviving, they must unravel the dark secrets of Harper Pass before those secrets can devour them.
