Duty Honor Planet is a rousing military science fiction tour de force that really gets you involved with the characters. I was impressed by how well the author crafted the various characters so that none of them were the two dimensional clichés you see in most military science fiction. You actually get to see the protagonist grow as an officer and a person.
The action is cinematic in scope and the ending was pulse-poundingly exciting. I highly recommend this book not just to fans of military sf but to anyone who likes a good adventure tale.
