The first novel by B.R. Young
The world was on the brink of inhabitation. A.I. were created to populate and restore the world while humanity retreated to farms far below the surface of the Earth, until such time as the world could sustain life once again.
The A.I. grew and learned, eventually enslaving the very humans that had built them. Now after centuries of living in the farms, humanity knows nothing of the world above. They are kept prisoners on the farms for a purpose no one knows. Red66 however is a decrepit A.I. with a human soul bent on giving humanity back its world and will stop at nothing to save them.
