Borogravia is at war. Again. When Polly Perks' brother goes missing in action, she cuts off her hair, stuffs a sock down her breeches, and enlists, hoping to find him. Passing successfully as a young man, she soon discovers that she's not alone in protecting a secret and that nothing in the improbable war is as it seems. Scrambling to survive both the enemy and their untried officer, Polly's misfit company makes its way to the front, where it might just prove to be the least likely regiment to ever win a battle. A wickedly funny look at the absurdities of war and ambiguities of identity.
