Summary: No one rattles Heath like his creepy cabin mate, Will Stringer. Brilliant, cold and calculating, Will views the world as one big chess game, and he’s always three moves ahead of everyone else. But Heath soon learns there’s a much bigger threat to contend with. Something’s wrong with the animals in the surrounding forest. A darkness is spreading, driving them mad with rage. They have one horrific goal: hunt and kill every human they find. Heath and a ragtag band of campers are faced with a choice: follow Will’s lead and possibly survive, or follow the camp staff and die. But how do you trust a leader when you suspect he’s more dangerous than the animals you’re running from?
