War rages on—with one unconventional soldier—in Terry Pratchett's bestselling Discworld® series
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 is 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 the army. Since a nation in such dire need of cannon fodder cannot 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 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.
Sir Terry Pratchett was the internationally bestselling author of more than thirty books, including his phenomenally successful Discworld series. His young adult novel, The Amazing Maurice and His Educated Rodents, won the Carnegie Medal, and Where's My Cow?, his Discworld book for “readers of all ages,” was a New York Times bestseller. His novels have sold more than seventy five million (give or take a few million) copies worldwide. Named an Officer of the British Empire “for services to literature,” Pratchett lived in England. He died in 2015 at the age of sixty-six.
