War has come to Discworld ... again.And, to no one's great surprise, the conflict centers around the small, arrogantly fundamentalist duchy of Borogravia, which has long prided itself on its unrelenting aggressiveness. A year ago, Polly Perks's brother marched off to battle, and Polly's willing to resort to drastic measures to find him. So she cuts off her hair, dons masculine garb, and -- aided by a well-placed pair of socks -- sets out to join this man's army. Since a nation in such dire need of cannon fodder can't afford to be too picky, Polly is eagerly welcomed into the fighting foldalong with a vampire, a troll, an Igor, a religious fanatic, and two uncommonly close "friends." It would appear that Polly "Ozzer" Perks isn't the only grunt with a secret. But duty calls, the battlefield beckons. And now is the time for all good ... er ... "men" to come to the aid of their country.
