Intending to establish a canon for the controversial slipstream science-fiction subgenre, the editors of this anthology have brought together a group of convention-defying tales set in vivid and disorienting dreamscapes that offer no distinction between reality and hallucination. A cross between the literary surrealism of Franz Kafka and escapist-popular-fiction, this ambitious new species—sometimes also called interstitial fiction—is exemplified here in stories by Carol Emshwiller, Karen Joy Fowler, Jonathan Lethem, and George Saunders.
