"A Tom Doherty Associates book."

"After the collapse of the world economy, a young boy grows up in what used to be Texas as a tough duellist for hire, the future equivalent of a hired gun. But even after the collapse, there is space travel, and he leaves Earth to have adventures in the really wide open spaces. But he is quickly catapulted into the more distant future, while humanity, and Artificial Intelligence, grows and changes and becomes a kind of superman"--,Provided by publisher.
