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.
