The first section of the volume addresses general topics, such as the history and origins of the genre, its engagement with science and gender, and national variations of science fiction around the English-speaking world. It also maps out connections between science fiction, television, the cinema, virtual-reality technology, and other aspects of the culture. The next section is devoted to major figures, such as H.G. Wells, Arthur C. Clarke, and Ursula Le Guin. Finally, the Companion offers close discussions of key novels, from Mary Shelley's Frankenstein to Margaret Atwood's The Handmaid's Tale.
