After the Fireflood - John Walters - Bog

During the Fourth World War, the entire Earth is engulfed in a torrent of fire, transforming the landscape and obliterating all life. Using terraforming, time travel, and other expediencies, human survivors from Moonbase and the outer colonies attempt to cope with their devastating loss, reconstruct the Earth's surface, and reorganize Earth sociologically to ensure lasting peace, while others plot to claim the pristine reconstituted planet for their own purposes.
