Molly Moon is unstoppable! She's a master hypnotist, a time-traveller and a mind-reader, and in this sizzling story she harnesses a new power - morphing. Soon she and her twin brother Micky are swapping bodies with ladybirds, rats, even the Queen of England herself! But the fun can't last forever ...and unless they can get their hands on the 'The Advanced Arts' hypnotism book, they will never get back to their own bodies. Sabotaged by a gaggle of wicked women who want to destroy them, Molly and Micky must find a way to return to themselves in spite of all the dangerous surprises thrown in their way.
