Welcome to the future: the utopian dreams and dystopian nightmares of British science fiction. Two of the most famous works of science fiction ever are British: Aldous Huxley's Brave New World and 1984 by George Orwell - books so important they've entered the language. One is a vision of the future full of sex and shopping; the other is a story of oppression and violence. But why have the British been better than anyone at imagining these future heavens and hells? And what do they reveal about us and our deepest fears? Contributors include Margaret Atwood and Iain M. Banks.
