The span of mainstream and science fiction

"This book examines works by Thomas Pynchon, Doris Lessing, and others who incorporate science into fiction and exemplify the movement of mainstream fiction writers toward a new genre herein termed "span." It also examines works by some science fiction writers who are edging closer to the border of science fiction and slowly over into spain. This book maps the boundaries of the new span genre of fiction and thus helps define texts that fall outside the realms of mainstream and science fiction."--BOOK JACKET.
