Query: Just great

I have never read a Terry Pratchett book before (except from half of Moving Pictures), but I think I might start now, since Witches Abroad is definitely one of the best books I've ever read. I particularly liked Granny Weatherwax, who is one of the greatest characters I've ever met in a book in the sense of having flaws and behaving badly and still being someone you just have to like. There are a lot of great scenes in the book, like Granny playing cards on the boat and her fight with Mrs Gogol, who is another wonderfully drawn character, too. So if you ever wondered about what makes stories happen, or what it really means to be a fairy godmother, just buy this book!
