Tiffany Aching lives on a farm, is good at making cheese, and is a girl of uncommon sense. She also dreams of becoming a witch (\"She preferred the witches to the smug handsome princes and especially to the stupid smirking princesses, who didn't have the sense of a beetle.\").
The Wee Free Men are the Nac Mac Feegle, tiny, redheaded, blue men in kilts, who speak in a thick Scottish brogue Pratchett invented for them, specialize in \"stealin' and drinkin' and fightin'\", and are perfectly described by one Amazon customer as \"foul-mouthed Scottish smurfs.\"
Tiffany sets out to rescue her baby brother, who has been kidnapped by the Queen of Fairyland, armed only with an iron frying pan and a book of sheep diseases, and accompanied by the brawling, boisterous Nac Mac Feegle. But more than her brother is at stake. This Fairyland is not the nice kind, full of buttercups and Tinkerbelles; it is a place of endless winter where nightmares come true, and where a person can be trapped in a dream forever. And it is encroaching on Discworld, threatening to absorb it.
A witch named Miss Tick offers Tiffany some terrific advice: \"If you trust in yourself ... and believe in your dreams ... and follow your star ... you'll still get beaten by people who spent their time working hard and learning things and weren't so lazy.\"
