This is the second book in the Rule Series. A new hunter shows up in Bliss, and she's determined to get her hands on Jack, despite Silver's protests. The head werewolf has left town... or has he? Jack suspects Jersey is spying on him and building an army to defeat him. In the meantime, Billy is hunting a dangerous pack on his own. When he disappears, they all think he's dead. But it's worse than that. Will Jack and Silver be able to survive the growing werewolf army?
