Firstly, if you've seen the movie adaptation of this book it is an entirely different story. Other than keeping character names it seems they changed virtually every aspect of the story.

I listened to this book with my son on audiobook, narrated by David Tennant and it was very fun. Tennant did a wonderful job and for me probably added another star to my rating. My 11 year old gives it 5 stars. :) A great fun middle grade read.
