Prelude to Foundation (57 page)

Nemesis

In the twenty-third century, pioneers have escaped the crowded Earth for life in self-sustaining orbital colonies. One of the colonies, Rotor, has broken away from the solar system to create its own renegade utopia around an unknown red star two light-years from Earth: a star named Nemesis.

Now a fifteen-year-old Rotorian girl has learned of the dire threat that Nemesis poses to the Earth’s people—but she is prevented from warning them. Soon she will realize that Nemesis endangers Rotor as well. And soon it will be up to her alone to save both Earth and Rotor as—drawn inexorably by Nemesis, the death star—they hurtle toward certain disaster.

Nightfall

(written with Robert Silverberg)

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. Now Dr. Asimov has teamed up 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.
