I bought this book for my grandson's 5th birthday, however his 6 year old sister; a confident reader, took a liking to it straight away, reading it cover to cover and laughing out loud. She also read it to any one who came to the house pointing out the amusing illustrations and 'extras' in case they didn't get the joke.
A straight forward story for the very young it is the added bits, maps, news cuttings, etc, that will keep older children amused, as they did me.
I have bought a previous book by this author which was enjoyable, but this one had more to it. I would definately recommend it.
