Monstrous Regiment

Monstrous Regiment by Terry Pratchett. mass_market edition. ISBN: 9780060013165.

War has come to Discworld ... again. And, to no ones 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 Perkss brother marched off to battle, and Pollys 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 mans army. Since a nation in such dire need of cannon fodder cant afford to be too picky, Polly is eagerly welcomed into the fighting fold—along with a vampire, a troll, an Igor, a religious fanatic, and two uncommonly close "friends." It would appear that Polly "Ozzer" Perks isnt 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.
