Katniss Everdeen has her bow and arrow; Tiffany Aching has her frying pan. The young protagonist of The Wee Free Men fights to save her little brother with ingenuity and daring in Terry Pratchett’s first book about her, which exists in his sprawling and massively popular Discworld series. Pratchett’s tale is well-paced, uproarious and filled with memorable monsters. But what pushes the novel into legendary territory are the titular wee free men: six-inch-tall pixies with Scottish accents who, in Pratchett’s own words, “have seen Braveheart altogether too many times.” They swear, brawl, steal and unite to aid Tiffany on her mission.
