In a paranoid Britain, Kyla, unable to save Cal, is now alone and hiding from the oppressive authorities, but even she can't avoid the ruthless Counterinsurgency and Anti-Terror Squads or CATS.

Instead of imprisoning her, CATS cuts her a deal. They want to brainwash Kyla and use the talents that make her elusive - her athletic ability, cunning and quick thinking - to turn her into a valuable asset of their own . . . hunting down the very people fighting for her freedom.

Will Kyla be able to escape? Or will she succumb to the villainous CATS and betray everyone?
