Earth is no more a home for mankind, it's still there as a white blazing star - a monument to the stupidity of man. The human race isn't extinct, it survived on the planet Venus. The planet had been undergoing terra forming when the earth was destroyed, thankfully that project was advanced enough to support survivors of Earth. But life on Venus isn't a picnic, temperatures are high and all flora and fauna, imported or local, are hell bent on destroying man. Add to that the greedy people who hire men to make war on the other keeps and shelters of man. A couple of very good stories by Master Author, David Drake.
