It was a sudden strange fancy ... and now Polly Perks, in her brother's clothes and her hair cut off, has joined up to fight for her country, just like the song says. But who is the enemy? What is she really fighting for? Why does she need a rolled-up pair of socks? War teaches you a lot, she finds, when it turns out that you joined ... the Monstrous Regiment.
