I am trying to remember the title of one of my favour science fiction books from the 1990s. It began with an astronaut sent to the stars returning decades later to an Earth empty of people. He finds a computer terminal and gradually dormant dopiter systems wake up and start to find out what happens.
Initially the only working computer function is a story telling module which starts trying to explain what happens. The story moves back in time as the computers search records and focus on a character called (from memory) Peter Devos or similar who starts to dream about a frozen girl on a spaceship. The story is complex and I really want to read it again.
