Georgia Byng2010

Molly Moon is unstoppable! The eleven-year-old orphan with dazzling hypnotic powers has discovered à whole new talent ... MORPHING! Soon she and her brother, Micky, are swapping bodies with ladybirds, dogs, rats, even the Queen of England herself! But fun can't last forever. If they don't find the world's only copy of The Advanced Arts of Hypnotism they'll never get back into their own bodies. And it doesn't help that they are being sabotaged by a strange group of people intent on destroying the world... and that the weather is behaving VERY oddly indeed.
