Noble values sewn into a captivating story.
This is the second book in the Tiffany Aching series (after The Wee Free Men and before at least a couple more with the tentative titles of Wintersmith and When I Am Old I Shall Wear Midnight).
Tiffany is now eleven, two years have passed since the events of The Wee Free Men and the incident with the Fairy Queen. She's learnt a few tricks since then, like the ability to step out of her own body, which is actually very handy when your only mirror is too small and you want to check if your hair is well combed at the back of your head. Although she likes wearing that invisible hat Mistress Weatherwax gave her.
Now Miss Tick the witch is bringing her to the mountains, to Miss Level's cottage to be more precise, an old witch with two bodies, where she shall begin her apprenticeship.
Her news friends, the other witches' apprentices, and especially Annagramma Hawkin, mock her because she's only good at sheep and cheese, and Miss Level only helps old people or acts as a midwife and she's not even doing proper magic, and of course Tiffany's not even wearing proper witch clothes with stars and sequins, let alone a real witch hat. In the end, Tiffany's apprenticeship turns out to be not exactly what she expected, but much, much more.
And all that time, the little blue fairy men, the Nac Mac Feegle, are watching over her. And what they find out is that an evil spirit, a Hiver, is pursuing Tiffany, waiting to take up her body the next time she steps out of it. Rob Anybody and his mates set out to help her.
I really really love the Tiffany Aching books. In them, and probably because they're aimed at a younger audience, Terry Pratchett manages to philosophize in a much more accessible and discreet manner than in his lastest (adult) Discworld books (like Thief of Time). The values he teaches here, through the relationship between people, or between people and the land, are very noble ones, and they're seemlessly sewn into a storyline that is in itself very captivating, and of course very funny. I really really love the Tiffany Aching books.
