I listened to the audio CD of this book before intending to send it to my grandson. It is fun and entertaining. However I will not be sending it to him as the book has a sad end. He would be in tears ). If I were to read this book to my 8 year old grandson I would change the end to Granny moving into an Old Folks home where she spends her days tunnelling out just like in The Great Escape) using plastic spoons from the dining hall that she steals every breakfast time. For me, it is a good, original story spoilt by a sad end.
