Tiffany Aching, a witch in training, leaves Chalk to go and work for Miss Level (a witch with two bodies) doing chores around the village. Petulia, a pig witch in training takes Tiffany to a small group of witches in training, led by Annagramma, a bossy witch in training who is disliked by most of the group. Tiffany tells the group about the imaginary hat she has but the girls don't believe her. Tiffany goes back to Miss Level's cottage and shuts herself in her room. Shut in her room, the hiver attacks Tiffany and takes her over. The hiver steals Mr Weavall's money, kills one of Miss Levels bodies and scares Annagramma. The Nac Mac Feegle start a mission to kill the hiver. The Feegles go inside Tiffany's head and find out that they must find three particular objects to wake the real Tiffany up: sheep's wool, turpentine and Jolly Sailor tobacco. Tiffany fights the hiver out of her head but the hiver is not dead...
The hiver is a creature that goes into the head of powerful people and takes over them. Everyone the hiver takes over becomes part of the hiver itself. When the hiver left Tiffany's head a bit of another of the hivers victim was stuck in Tiffany's head. The hiver cannot be killed.
I like Oswald, a spirit that helps around the house.
