A story about "Harry Potter and the Prisoner of Azkaban" — 7 years ago
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 ;)
