'A true genius ...Roald Dahl is my hero' - David Walliams Phizzwhizzing new cover look and branding for the World's Number One Storyteller! George Kranky's Grandma is a miserable grouch. George really hates that horrid old witchy woman. One Saturday morning, George is in charge of giving Grandma her medicine. So-ho! Ah-ha! Ho-hum! George knows exactly what to do. A magic medicine* it will be. One that will either cure her completely ...or blow off the top of her head. *Warning: Do not try to make George's Marvellous Medicine yourselves at home. It could be dangerous. Now you can listen to George's  Marvellous Medicine and other Roald Dahl audiobooks read by some very famous voices, including Kate Winslet, David Walliams and Steven Fry - plus there are added squelchy soundeffects from Pinewood Studios! And look out for new Roald Dahl apps in the App store and Google Play- including the disgusting  Twit or Miss! and House of Twits inspired by the revolting Twits.
