Black Magic

Today, the planet Venus is a literal hell of furnace-like temperatures and dense, poisonous atmosphere. But millions of years in its past, Venus teems with life and with a civilization far advanced to our own. The Nemisis supercomputer controls government functions, with bioroid "executors" created to carry out the system s utopian edicts. But trouble brews even in paradise, as different executors vie for control of Nemesis, forcing the governing system to secretly create Duna Typhon, a super-bioroid "sleeper," raised among the human populace, ready to use her awesome powers should Nemesis be co-opted to turn paradise into paradise last."
