When humanity is driven to extinction by a deadly virus the only intelligence left on Earth is artificial. These super computers and synthetic beings eventually form their own society and begin to build more of their kind as they clean up the planet. But their world becomes more complicated when one synthetic scientist creates a hybrid clone of a human being. Slowly, humans begin to repopulate this A.I. world. Things become even more convoluted when a group of aliens arrive wanting to immigrate to Earth.
A storyline never before tacked in science fiction by the author of such classics as Evergreen, Red Sky Blue Moon, and Monster Town.
