Harry Potter and the Prisoner of Azkaban is the one that I personally enjoyed most amongst the Harry Potter series.

 

In this third book, Harry is no longer a child but a proper teenager who begins to get the bitter sweet flavour of adult world. Life does not work like as it does in a fairytale. For the first time in his life, Harry meets someone who is almost like a parent to him (his godfather, Sirius) and even, however briefly, gets to entertain the thoughts of living with him. However, the opportunity is snatched away from him as soon as it has been given to him. Harry saves Sirius and sends him away to protect him.

 

What intrigues me most while reading the book was that Harry, for the first time, displays his hatred (his pent up emotions) to whom he thought was his parents' killer. In doing so, he becomes more real, and more human-like than he has been in the first and the second book. In those previous books, he had too much characteristics of the other ordinary story books. He used to act too mature for a low-teen and seemed to put someone else's feelings and needs before his own.

 

From the first book, perhaps because he meets with his godfather who wants to spoil him and care for him, Harry becomes a little more selfless than he used to be.

 

That, for me, was kind of relieving.
