Great Fairytale Robbery [PDF ebook] 

Sarah and Julie switch on the television: instead of the movie they expect, they see a crowd of their favourite storybook characters, including Cinderella, Puss-in- Boots, Aladdin, Bo Peep and Hansel and Gretel, calling out for help. So the two girls step into the fantasy world beyond the TV screen and find themselves involved in a battle of wits against the witchlike Studio Head, whose ambition is to destroy all books. Oz, Julie’s life-size rag doll, dreams up a plan to save the fairy tale people from fading away… to Studio Head’s dismay.
