An interesting tale of a millenial war and the soldier who participates in all of it thanks to relativity effects of space travel. Clear parallels to Vietnam and some clever ideas here. My main gripe is that the narrator and main character is the only person who feels at all real. Everyone else, even the woman who is supposed to be the love of his life, just feels like set dressing. But if plot and theme are important to you and you aren't bothered by a little bit of weakness in characterization, its an enjoyable read.
