Framed for the murder of an influential leader, Section 9 is left scattered and exposed deep within hostile territory. Tycho and Section 9 must now cross the eastern half of the divided city to reach the safety of the west. Along the way, enemies of all kind will hunt them, including corporate enforcers, syndicate bounty hunters, and a specialized unit of monstrous technological chimera. With enemies on all sides, Tycho has little hope of survival. But Arbiters are made to defy death, and Tycho is no exception.
