Query: NOT AS GOOD AS THE FIRST, BUT A VERY GOOD BOOK!

I enjoyed reading Harry Potter and the Prisoner of Azkaban. It made me feel like I was in his world. There is a lot of action in the book. I loved reading it. The new charactors in the book, are exciting to read about. When Snape comes along it gets exciting. It is a cool book!
