There were two: Rosslyn, the pilot, and Comain, the dreamer. Rosslyn died in space, frozen, preserved for two centuries until found and resurrected by a miracle of future surgery. Comain . . . ?Comain remained on Earth and crystallised his dreams, and when Rosslyn returned he found a civilisation beyond his wildest imaginings. Women ruled the planet, guided solely by the automatic and relentless predictions of a tremendous and frightening machine. A machine that foretold the future and determined the actions of an entire world with devastating accuracy. Into this assured and new civilisation Rosslyn came – and the impact of his presence brought near chaos.He had to be assimilated – or eliminated.
