Lucy didn't come to school the day after hide-and-seek. Without his best friend, Ben's life has changed forever. He no longer feels safe playing outside at night like the other kids of Elkwood, Missouri. As he makes new friends who stick with him throughout high school, Ben just can't seem to shake his dread of being outdoors after sundown. Maybe Ben's just paranoid. After all, nobody else is vanishing... until they are.

Someone or something is stalking the trees at night. A girl has been found mauled to death. The only survivor isn't sure what attacked him. And, who knows if what's out there now is the same thing that took Lucy all those years ago?
