Since childhood he has dreamed of a beautiful young woman. His fate, he sees, is to rescue her from captivity--and perhaps save the whole world, now moved into the outer solar system and lit by a string of tiny orbiting suns.He has yet to meet his true foe, the dragon whose history stands opposed to humankind's. But which will prove to be this world's mythic Galahad?
