About the AuthorSALES POINTS * #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
