Crisis on the Moon! Both worlds were falling apart as they watched.          The Earth was devastated by a total collapse in the year 2048. After a partial recovery by 2063, a secret laboratory creates Gwyn: a clone who gets a powerful computer implant, becoming a cyber super-human of sorts. He and others try to help the large Moon colony and a smaller colony on Mars succeed, while the Earth faces mass suicides and steep environmental declines, making it difficult to support the colonies.          Interleaved into the story is a second part taking place 800 years later. Jun Arakras lives in a habitat at an Earth-Moon Lagrange point. Such habitats were built by the mysterious Builders, who had mastered technology and built perfect, self-maintaining habitats, but then disappeared. Humans on Earth are slowly recovering their earlier technology, while those in habitats are degenerate, since each habitat takes complete care of them. Jun must first face pirates who raid habitats for supplies, to kill and pillage, and to take slaves. She ends up travelling to the huge Moon habitats to somehow establish a new order.          As it was 800 years before, both the Earth and the Moon again face crises. For humans in the solar system, the missing Builders are the greatest mystery. Are they gone for good or have they secetly remained?
