Curiosity was discouraged in the Greene tribe. Its members lived out their lives in cramped Quarters, hacking away at the encroaching ponics. As to where they were—that was forgotten. Roy Complain decides to find out. With the renegade priest Marapper, he moves into unmapped territory, where they make a series of discoveries which turn their universe upside-down… Non-Stop is the classic SF novel of discovery and exploration; a brilliant evocation of a familiar setting seen through the eyes of a primitive. ‘Our ablest SF writer.’ ‘A brilliant treatment of the generation starship and also the theme of conceptual breakthrough; it has become accepted as a classic of the field.’ ‘Non-Stop offers a number of conventional sf pleasures, but it does more… it refuses to resolve itself into a happy, wish-fulfilling ending. The characters discover that they are the victims of a cosmic joke: ironies abound, the struggle goes on.’
