David Walliams' novels have had such a huge impact on children's fiction that now many people see the actor, comedian and fundraiser as an author first. Full of heart and humour, his stories look at issues that affect all children and have devilishly Dahl-style anarchy running through them.Following the success of Demon Dentist, Mr. Stink and The Boy in the Dress, we're delighted to be offering you his latest bestseller, Grandpa's Great Escape. Jack's Grandpa may wear his slippers to the supermarket and constantly forget Jack's name but he can still take to the skies and save the day.With spitfire journeys over London and great escapes through the city, this is an exciting adventure about the bond between grandparent and grandchild. It's also full of Walliams' long-time collaborator Tony Ross' distinctive illustrations.
