Puffin Audiobooks present a phizz-whizzing reading of Roald Dahl's George's Marvellous Medicine, read by Derek Jacobi. The audiobook features original music and 3D sound design by Pinewood film studios.

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.
