Disputes over the meaning and practice of sexuality have become increasingly central to cultural self-definition. It is hardly surprising, then, that science fiction, the province of new physical and psychological frontiers, has taken up the task of imagining a diverse range of queer and not-so-queer futures. Queer Universes is a landmark investigation into these contemporary and historical representations of gender and sexualities—including Wendy Gay Pearson’s award-winning essay on reading science fiction queerly, as well as essays discussing “sextrapolation” in New Wave science fiction, “stray penetration” in William Gibson’s cyberpunk works, the queering of nature in ecofeminist sci-fi, and the radical challenges posed to conventional science fiction in the work of important writers such as Samuel R. Delaney, Ursula K. Le Guin, and Joanna Russ. In addition, this distinguished volume offers interviews with acclaimed science fiction writers and essays from scholars and science fiction giants alike.“Timely, smart, and innovative, this vital collection ensures that our conception of science fiction is fuller and healthier.”—Science Fiction Studies
