Why did Isaac's father have to die so young? Isaac's older cousin Charlie—a science teacher—says he knows why. Nature is pitiless. There's no God. No afterlife. Just atoms in the void and the struggle for survival. Charlie says a week at their grandparents' farm, seeing animals get killed and eaten, will prove it. But at the farm, both of them get more than they bargained for. And soon Isaac finds himself caught in a battle of wits between two men, and facing a choice he alone can make.
