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 Earth's people--but she is prevented from warning them. Soon she will realize that Nemesis endangers Rotor as well. And so 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.

A millennium into the future, two advancements have altered the course of human history:  the colonization of the Galaxy and the creation of the positronic brain.  On the beautiful Outer World planet of Solaria, a handful of human colonists lead a hermit-like existence, their every need attended to by their faithful robot servants.  To this strange and provocative planet comes Detective Elijah Baley, sent from the streets of New York with his positronic partner, the robot R. Daneel Olivaw, to solve an incredible murder that has rocked Solaria to its foundations.  The victim had been so reclusive that he appeared to his associates only through holographic projection.  Yet someone had gotten close enough to bludgeon him to death while robots looked on.  Now Baley and Olivaw are faced with two clear impossibilities:  Either the Solarian was killed by one of his robots--unthinkable under the laws of Robotics--or he was killed by the woman who loved him so much that she never came into his presence!

These two renowned writers have invented a world not unlike our own--a world on the edge of chaos, torn between the madness of religious fanaticism and the stubborn denial of scientists. Only a handful of people on the planet Lagash are prepared to face the truth--that their six suns are setting all at once for the first time in 2,000 years, signaling the end of civilization!.
