Molly Moon is on a mission – to bring her long-lost twin brother, Micky, home. But before she can rescue him she has to FIND him, and he could be anywhere! Luckily Molly’s time-travel talents and world-stopping skills help her in her search . . . until a baby-faced villain with a precocious plan to have the world’s biggest brain gets in her way. Can Molly, Petula the pug and their best friend, Rocky, use Molly’s new secret weapon – MIND READING – to defeat the brainy babe and her monstrous mind machine?

Eleven-year-old Molly Moon is known and loved for her incredible powers - hypnotism, time travelling, mind reading . . . But now something seems to have power over her. Not only has it made her a brilliant musician, it's given her thousands of new fans, all of whom are mesmerized by her. Literally. Only Petula, her pet pug, senses an off-note. Molly-the-Maker-of-Magical-Music is one thing, but Molly-the-Big-Old-Meanie is another - and every day Petula sees her kind owner become more and more horrible. What is going on? And can one determined dog sort it out . . . before Molly becomes truly monstrous?

Orphan Molly Moon was found as a baby in a box marked 'Moon's Marshmallows'. For ten miserable years she's lived under the cruel rule of Miss Adderstone in grim Hardwick House. But her life changes overnight when she finds a mysterious book on hypnotism and discovers an amazing talent - the power to make people do anything she want them to. Escaping from the orphange, Molly flies to New York in search of fame and fortune. But her adventures in hypnotism lead her into the clutches of a dangerous enemy . . .

Molly Moon has just found herself in the wrong place at the wrong time! A conniving, super-rich maharaja has abducted Molly and Petula the pug and whisked them back to nineteenth-century India. Using the art of Time-Travel Hypnosis he has also kidnapped four younger versions of Molly, as part of a plan to stop Molly ever learning her hypnotic skills. With not only her past but the future of the world at stake, can Molly outwit the cunning maharaja before it's too late?
