Ok… I love the HP books but I think the real story starts with book 3: many things happen that leash the events of next books.
PoA also introduces to two beautiful characters such as Sirius Black and Remus Lupin: one can help to fall in love with any of them (or both!).
This book is waaay worthy… and still the favourite of the Potterhollics ;)

I wanted a video for Christmas of 1992, but I got two books instead: Journey… was one of them. I read it next day and I loved it! Then I read it again and again and again… I only wished I could have had the same adventure in my mind and wonder why has no one ever done this?
Terrific!
