Doubleday Science Fiction When a writer sits down to create a science fiction story, he can count very little help from his own concrete experience, for his business is exploring worlds we don't know. In none of these worlds is there much we can take for granted - all the common-places of daily life in them must be made explicit. For this reason, among others, the short novel is the best length for a work of science fiction. It gives the writer space to develop the complexities of his ideas, examine its implications and make the unreal world of the story as familiar to the reader as his own. Frederik Pohl, now editor of *Galaxy Magazine* and himself a master of science fiction, has put together a collection which shows how good this genre can be - and demonstrates the high quality of the material published by *Galaxy* Contains: Introduction / Frederick Pohl Time Waits for Winthrop / William Tenn Accidental Flight / F. L. Wallace To Marry Medusa / Theodore Sturgeon Natural State / Damon Knight Galley Slave / Isaac Asimov
