Well, have just finnished reading the third Harry Potter book, The Prisoner of Azkaban, I enjoyed it very much.
The film, which I had just watched a few days ago was very enjoyable, but so many of the little details that make the Potter world what it is were cut from the film. The book fleshes out the story, making it that much richer.
I loved the book very much. The feelings I got from reading the book reminded me of when I first read the Lord of the Rings. Potter (the book, not the character) even smells the same.
So, what now? Book five beckons.
