After reading 'A Friend Like Henry' and 'Marley and Me' I couldn't wait to get stuck into another K9 book. I must say in comparison with these other 2 books I was disappointed with the content. It didn't keep me wanting to read on, the story wasn't as gripping. I quite happily set the book down at bedtime and didn't think about it again til the next night. That said, I did enjoy the book just not as much as the others.
I haven't stopped here though, I am already into my next K9 book.
