Harry Potter and the Prisoner of Azkaban (Book 3)

Harry Potter and the Prisoner of Azkaban - J.K. Rowling, Mary GrandPré Probably one of my favourite books of Harry Potter. I really enjoy the movie as well. From this book onwards the tones change a lot and that feeling of a classic dissapears.

Don't forget that each book is a year in Hogwarts, which every year Harry and his gang are a year older so the books also grow. I think JK Rowling did that interesting enough.

But for me, the three first books are the best. No doubt about it. Those are books I really want my unborn child to read as he grows up.
