Stories of imagined futures abound in Western writing. Writer and editor Nalo Hopkinson notes that the science fiction/fantasy genre "speaks so much about the experience of being alienated, but contains so little writing by alienated people themselves." It's an oversight that Hopkinson and Mehan aim to correct with this anthology. The book depicts imagined futures from the perspectives of writers associated with what might loosely be termed the "third world." It includes stories that are bold, imaginative, edgy; stories that are centred in the worlds of the "developing" nations; stories that dare to dream what we might develop into. The wealth of postcolonial literature has included many who have written insightfully about their pasts and presents. With So Long Been Dreaming they creatively address their futures.
