Relaunch of spectacular Robert Westall fantasy novel that was way ahead of its time.

A fantasy of the near future in which Britain is divided into Zones and castes to which men and women are pitilessly allocated at the end of their schooling. Whether crazed proles in the Unnem zones, smug pampered bourgeois Ests or arrogant Techs, all are ultimately pawns of the computer that governs it all. One boy penetrates the conspiracy by which the nation is governed and has the knowhow to strike at the heart of evil.
