Long before the start of this exciting novel, all life on Earth has been decimated by the impact of a gigantic asteroid. But before the devastating collision, a small group of survivors escape to the moon, where genetic clones of themselves then slumber for millennia. When alien starfarers arrive, together they must undo the damage and rebuild the Earth's ecosphere so that humans and aliens alike, can live on the planet.

Serialized in Science Fiction Age and Analog magazines, Terraforming Earth is a story of struggle and adventure in a far future whose history stretches back for millennia and whose civilization spans the stars. A fascinating future, where sentient beings and machines, trying to rebuild a new, different Earth, race against time to save what's left of humankind's ancient legacy before it's destroyed forever.
