Query: FANTASY OR SCIENCE FICTION?

There is a point where science fiction becomes fantasy, and Greg Egan passes that point with a vengeance. The mostly speculative physics is just that, speculation, fantasy run amok! The plot was poor, and character development was atrocious. I could feel no sympathy for, or identify with, any of the characters. The only good parts of the story were where mind transfers took place, this idea was well done here, but for an even better treatment of that read THE FIRST IMMORTAL by James Halperin, a very good novel.
