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.
