About the book
Eleven-year-old Tiffany Aching leaves the Chalk to learn witchcraft from Miss Level in the mountains, where her apprenticeship involves chores and caring for people who need a witch’s help. Other young witches seem far more certain about how to dress and behave. Meanwhile, an invisible creature called a hiver has noticed Tiffany’s unusual power and is following her, threatening something that spells and the Nac Mac Feegle’s fists cannot easily protect.
Reader notes
Dry wit and the Feegles’ rowdy antics alternate with quieter passages about insecurity, responsibility and the unglamorous work of helping others. This second Tiffany Aching adventure is YA comic fantasy, but its interest in what makes someone capable or kind extends beyond the magical danger.

Is it hard to read?
No, the conversational, direct prose and linear story keep it approachable. The greater demands come from the ideas Tiffany encounters: responsibility, insecurity, and how to use power kindly.
Is it funny or serious?
Dry wit and the Feegles’ rowdy antics alternate with quieter passages about insecurity and responsibility. The tone is warm and humorous, with suspense from the invisible hiver following Tiffany and threatening her unusual power.
What does learning witchcraft involve?
Tiffany’s apprenticeship involves chores and caring for people who need a witch’s help. Alongside the magical danger, the story explores the unglamorous work of helping others and what makes someone capable or kind.
Is it only for younger readers?
No, it is YA comic fantasy with an eleven-year-old heroine, but its interest in kindness, capability and responsibility extends beyond the magical danger. Tiffany’s uncertainty around more confident young witches also gives identity a central place.

About the author
Terry Pratchett
Terry Pratchett was an English fantasy novelist whose career began with The Carpet People and became centered on the long-running Discworld series. Starting with The Colour of Magic, Discworld developed from a broad parody of sword-and-sorcery conventions into a more flexible form of comic satire. Pratchett built stories around familiar fantasy machinery such as wizards, dragons, gods, and Death, then used it to examine institutions and ordinary social behavior. His method combines brisk plots, conversational wit, absurd premises, and characters whose practical weaknesses often prove more revealing than heroic competence. Guards! Guards! turns a dragon story into an inquiry into civic authority and policing, while Small Gods brings organized religion and sincere belief into conflict through a god trapped in the body of a tortoise. Mort similarly makes Death’s apprentice confront rules that appear fixed by fate. The result is fantasy distinguished by its alertness to power, faith, bureaucracy, and human folly, while remaining accessible as comedy.
