The Shepherds Crown
by Terry Pratchett
Tiffany Aching is busy running her steading and taking care of the people of the Chalk. Jeannie, the Kelda of the Nac Mac Feegle, is worried that she's overworked. When Granny Weatherwax, Tiffany's mentor, dies, she leaves everything to Tiffany, who becomes the first among equals of the witches.
Geoffrey, the third son of Lord Swivel, is well educated, vegetarian and a pacifist. He is dissatisfied with hunting practices he considers barbaric, and after a confrontation with his father, heads towards Lancre, intending to become a witch.
Meanwhile, in the domain of the Elves, Peaseblossom senses that the passing of Granny Weatherwax has weakened the barriers between the realms. When a goblin shows the faerie court what the humans are capable of with iron and the status that goblins have achieved, Peaseblossom usurps the Queen, intending to reenter the human world and reestablish the elves' power.
Tiffany, spread thin tending to the Chalk and Granny Weatherwax's old steading, employs Geoffrey as a backhouse boy and starts teaching him. He and his goat get on well with everybody, and Tiffany dubs him a calm-weaver. Intending to help old men have some autonomy from their wives, he introduces the idea of sheds.
Nightshade, the former Queen of the Elves, is found by the Feegle stationed on the Chalk at the gateway to fairyland. Her wings had been ripped off before she had been forcibly ejected from her world. The Feegles restrain her until Tiffany arrives and takes her in on her family farm. While there, she decides to carry as a talisman the shepherd's crown, or fossilised Echinoid, that had been in the Aching family for many generations. Tiffany attempts to teach Nightshade what it is to be human and the motivations of kindness.
Tiffany gathers the witches to prepare for an invasion by the Elves. Geoffrey marshals the old men, and assembles a fighting force. Tiffany attempts to enlist the help of the Elf King. When that fails, she assigns the Feegles to build the King a shed in the hope that it will earn his allegiance.
The elves break through at two stone circles: up in Lancre and down in the Chalk. In Lancre, they are met by the assembled witches with help from Geoffrey and the men and they are defeated. In the Chalk, they are met by Miss Tick, Letitia, Tiffany, and the Nac Mac Feegle. Nightshade, with her glamour restored, fights for Tiffany, whom she now considers a friend, until she is killed by Peaseblossom. The elves seem to have the upper hand until Tiffany, wearing the shepherd's crown, calls the power of the Chalk to bring a storm and commands the ghosts of her grandmother's sheepdogs, Thunder and Lightning. She summons the King of the Elves, who kills Peaseblossom, and she banishes the elves from the Land.
Tiffany decides to devote herself to the Chalk. She recommends that Geoffrey be given Granny Weatherwax's steading, and hand-builds herself her own shepherd's hut, reusing the old iron wheels from her late Granny Aching's shepherd's hut.
