The Wee Free Men isn’t the best title for Terry Pratchett’s excellent book about a girl, Tiffany Aching, who becomes a witch-hero.
Like The Amazing Maurice and His Educated Rodents this is an excellent younger readers-focused book set in the Discworld but kind of off to the side somewhere. It has less to do with storybook tropes, and more with analysis of what a witch actually does.
Basically Tiffany Aching is a ten-year-old badass through her careful paying of attention to things and when her little brother (who she doesn’t really like) is kidnapped by otherworldly creatures she goes off to save him because who can wait for the “real witches” to show up? She’s got help from a toad (a bit) and the titular Wee Free Men, who are pictsies that fight and steal and cuss. They’re kind of awesome and stuff, but it bugs me that the book is named after the assistants, rather than the hero. I guess there are a lot of them, and they may have intimidated Sir Pratchett.
