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.
