Penguin presents a brand-new, downloadable audiobook recording of Roald Dahl's classic George's Marvellous Medicine. George Kranky is eight years old and wondering what sort of mischief he might get into. George's Grandma is a grizzly old grouch and George wants to teach her a lesson.... And when Grandma's finished drinking George's marvellous medicine, she'll really have something to grumble about.
