Description:

From Publishers Weekly

When Eugenia Insigna of the Settlement Rotor, an independent space station, discovers an unknown red dwarf star two light years from Earth, she names it Nemesis. Led by Dr. Janus Pitt, Rotor and its population travel to the star to build a new, morally pure society. Insigna's daughter Marlene, who can read body language like a telepath, learns that Nemesis is moving dangerously close to Earth's solar system. After trying to communicate her knowledge, Marlene discovers that a conspiracy is suppressing it. Told alternately from two points of view, Marlene's and (in a different time frame) her father's, the book is repetitive, talky and unengaging. Asimov is at his best when his characters discuss science and their schemes for saving Earth's people from destruction by Nemesis.

From Library Journal

A man's search for a daughter he has never known, a young girl's affinity for the mysterious planet around which her space station home revolves, and a space colony commissioner's desire to isolate his renegade community form the delicate framework upon which rests Earth's future. Although the prolific Asimov's forte lies in his dedication to hard science as the basis for his stories, his latest novel features an intriguing mix of believable heroes and villains, a pair of convergent plots, and a nicely foreshadowed conclusion. Highly recommended.

SUMMARY: 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.
