Mistreated orphan Molly Moon has a pretty miserable life, until she finds an old book on hypnotism in the local library. She decides that the possibilities are endless and sets about building a new life for herself. But she's not the only one who knows about the book...
I think I would have enjoyed this book a lot more when I was ten. Which is fair enough - that's the age group it's aimed at, after all. But after books for younger people by authors like Terry Pratchett and Diana Wynne Jones, which are enjoyable for adults too. this was a little disappointing.
