About the Author

41 in the Millennium SF Masterworks series, a library of the finest science fiction ever written. * 'Frederik Pohl, one of the old pros of the genre, never takes unnecessary risks. For him, science fiction is a form of play - an excusable indulgence since he plays it so much better than most people.' The New York Times Book Review * 'The most consistently able writer science fiction has yet produced' -- Kingsley Amis * 'One of Frederik Pohl's best novels - and my personal favourite. Complex people in tough situations on a marvelous and gritty world - who could ask for more from any novel?' Greg Bear Frederik Pohl was born in 1919 and has been professionally involved in sf as an editor and writer since his teens. Among his many books are A Plague of Pythons, Gateway, Man Plus and JEM: The Making of a Utopia. C.M. Kornbluth (1923-1958) was the bureau chief of a Chicago news agency until 1951 when he took up fiction writing full time. He established himself very quickly as a brilliant short-story writer with works such as 'The Little Black Bag', 'The Marching Morons', 'The Cosmic Charge Account' and 'Two Dooms'. Pohl and Kornbluth started writing stories together in 1940 and their collaborations include The Space Merchants, Search the Sky and Gladiators-at-Law.
