Weeks after his crucifixion and rebirth as Phoenix, Ash Fisher believes his troubles are far behind him. He and Natalie are engaged and life seems good. But his happiness is short-lived when he receives a threatening visit from Purian Rose, who gives Ash an ultimatum: vote in favour of Rose's Law permanently relegating Darklings to the wrong side of the wall or Natalie will be killed. The decision seems obvious to Ash; he must save Natalie. But when Ash learns about The Tenth, a new and deadly concentration camp where the Darklings would be sent, the choice doesn't seem so simple. Unable to ignore his conscience, Ash votes against Rose's Law, signing Natalie's death warrant and putting a troubled nation back into the throes of bloody battle.
