"This monster has come from the darkest and fieriest pits of hell. There is no other possible explanation."
-William Wilson, 2006
For William, this summer was supposed to be about finding his independence. Instead, it's become about survival. A week after his younger brother, Grey, vanishes with his entire class, William's grief is eclipsed by a new, creeping terror-a nightmare that refuses to end when he wakes up.
It starts with a flicker of impossible movement at the edge of the woods: a towering creature of bone and shadow, with hungry yellow eyes and three massive ribs protruding from its torso. Soon, the sightings become a relentless campaign of psychological warfare. It leaves gruesome gifts on his lawn. It taps at his window in the dead of night. It stands in the middle of a busy street, visible only to him.
As William's sanity frays, his friends dismiss his fears as stress, and the police see him as a delusional teen. Trapped in a world that refuses to see the monster in its midst, William is utterly alone. He is no longer just a grieving brother; he is the chosen prey in a terrifying hunt. And he is beginning to realize the creature doesn't want to just kill him. It wants him to break first.
