But a shadow from the urban waste breaks into Saul's prison cell and leads him to freedom: a shadow called King Rat. King Rat reveals to Saul his own royal heritage, a heritage that opens a new world for him, the world below London's streets.
With drum-and-bass pounding the backstreets, Saul must confront the forces that would use him, the ones that would destroy him, and those that have shaped his own bizarre identity.
