Isaac Asimov and Robert Silverberg. Stated first edition. New York: Foundation/Doubleday, 1990. Both unclipped dust jacket and hardcover are in Very Good+ condition. Jacket designed by Don Dixon. There is some minor chipping on top of spine. No writing or markings found in the book, 339 pp.
A fine example of this double-teamed expansion of Asimov's 1941 novel by the same name, of a star system with 6 suns which only experiences darkness once in two millennia. A sci-fi and Asimov collector's must-have.
The novel is based on a short story Nightfall by Asimov which first appeared in Astounding Science Fiction in 1941.
Nightfall is one of the classic stories of Science Fiction, "his most famous story and probably the single most famous US sf story of all time." - John Clute and Malcolm Edwards, SFE (online).
