What is the relationship between science fiction and social, political and sexual radicalism? Does science fiction open up margins for resistance and experimentation? What sort of discourse is science fiction? How can we best situate science fiction in terms of its historical context? Science Fiction, Critical Frontiers addresses these and other key current issues in science fiction studies. The collection includes the latest work by some of the major figures in contemporary science fiction criticism. It focuses on the major theoretical issues within science fiction as a genre, and provides examples of critical perspectives applied to specific texts. Many of these texts regularly appear on undergraduate science fiction courses.
