This book begins a few months after the first one ended and continues to follow Jack and Silver as they prepare for their battle with head werewolf Jersey Clifford. Jack's world is falling apart. Silver has told him she needs space, he might not graduate from high school, and he feels incredibly alone. Enter a new threat, a new enemy. The question is does she want to kill Jack or does she just want him?
