By 2185, research into genetics has made artificial humanoids easy to produce. The Android Complex in Denver has manufactured the most successful lot, the 900 Series. They are far more intelligent and resourceful than any of the previous series-enough so that they're able to escape from the complex, travel to Mars, and disappear into human society. Robert, a human member of the media on Mars, is kidnapped by a female android to aid her on a dangerous mission: a return to Earth to find and rescue the aging Dr. Ford, the creator of the 900 Series. Their quest leads Robert into a world he never even imagined, one where the old rules of space and time no longer apply.
