Nightfall

On a planet with six suns, night is about to fall for the first time in two thousand years... The planet Kalgash is on the brink of chaos - but only a handful of people realize it. Kalgash knows only the perpetual light of day; for more than two millennia, some combination of its six suns has lit up the sky. But twilight is now gathering. Soon the suns will set all at once - and the terrifying splendor of Nightfall will call forth a madness that signals the end of civilization. Isaac Asimov's short story Nightfall first appeared in 1941. It has since become recognized as a classic, its author a legend. But the short story isn't the whole story. Dr. Asimov has teamed with multiple Hugo and Nebula Award winner Robert Silverberg to explore and expand one of the most awe-inspiring concepts in the history of science fiction. In this novel, you will witness Nightfall - and much more. You will learn what happens at Daybreak.
