Monstrous Regiment Discworld Terry Pratchett 2003
Polly Perks joins the Discworld army to find her brother Paul.
Ozzer cuts off her blonde braids, dons male garb, belches, scratches, and masters macho habits aided by well-placed pair of socks.
The legendary and seemingly ageless Sergeant Jackrum accepts her plus a vampire, troll, zombie, religious fanatic, and two close friends. The best man for the job may be a woman.
