Non-Stop remains a brilliant and ground-breaking work of imagination. Curiosity was discouraged in the Greene tribe. It's members lived out their lives in cramped quarters, hacking away at the encroaching jungle called "the ponics." As to where they were--that had long ago been forgotten. But Roy Complain decides to find out, along with the renegade priest, Marapper. They move into unmapped territory, where they make a series of discoveries which turn their universe upside-down. They meet mutants and giants, regimented rats, telepathic rabbits, and the fabled Outsiders. And they confront a secret kept hidden for twenty-three generations--a secret whose discovery will reveal their origins and destiny even as it destroys their world.
