This book was the first of this length for my son to read from cover to cover by himself ... it was so good he didn't stop until he'd read the whole book in one sitting. Up until then it had been hard work getting him interested in reading anything longer than a couple of pages so this really was a major breakthrough. He laughed out loud and read bits out to me so that I could laugh too. We went on to get the whole series. All great, but soft spot for this one.
