Science fiction is at the intersection of numerous fields. It is a literature which draws on popular culture, and which engages in speculation about science, history, and all types of social relations. This volume brings together essays by scholars and practitioners of science fiction, which look at the genre from these different angles. After an introduction to the nature of science fiction, historical chapters trace science fiction from Thomas More to more recent years, including a chapter on film and television. The second section introduces four important critical approaches to science fiction drawing their theoretical inspiration from Marxism, postmodernism, feminism and queer theory. The final and largest section of the book looks at various themes and sub-genres of science fiction. A number of well-known science fiction writers contribute to this volume, including Gwyneth Jones, Ken MacLeod, Brian Stableford Andy Duncan, James Gunn, Joan Slonczewski, and Damien Broderick.
