Query: Rejuvination - at a cost

A unique take on the immortality-through-cloning plot - to get your 'rebirth' you have to sign up for the intergalactic armed forces. Though the story took a while to get going, seemingly because the author took too much time (or pleasure) in explaining how the immortality was going to work in his universe, once you get past the army cliches, the story becomes quite fun. I like the alien races he created, and how he imagined our interactions with them to be. The story really got GOOD in the last third of the book, so I expect the follow-on books to be just as good now that the universe is already explained.
