Driftglass is the definitive volume of his stories, featuring neutered space travellers, telepathy, Hells Angels and genetically modified amphibious workers. 'Delany's books interweave science fiction with histories of race, sexuality and control. In so doing, he gives readers fiction that reflects and explores the social truths of our world' The New York Times
