"In a dangerous future world where gigantic, motorized cities attack and devour each other, London hunts where no other predator dares. But Anna Fang -- pilot, adventurer, spy -- isn't afraid. These three stories show gripping, moving, exciting moments in Anna Fang's life: her childhood as a slave aboard the moving city Arkangel, a showdown against a robotic Stalker that is terrifyingly out of control, and her free life as an intelligence agent for the Anti-Traction league ..."."--Provided by publisher.
