When witch-in-training Tiffany Aching accidentally interrupts the Dance of the Seasons and awakens the interest of the elemental spirit of Winter, she requires the help of the six-inch-high, sword-wielding, sheep-stealing Wee Free Men to put the seasons aright.

A young witch-to-be named Tiffany teams up with the Wee Free Men, a clan of six-inch-high blue men, to rescue her baby brother and ward off a sinister invasion from Fairyland.

After generations of existing in the human-sized world, a group of four-inch-high nomes discover their true nature and origin, with the help of a black square called the Thing.
