I offered for Christmas this book to my daughter who is a fan of Harry Potter from the beginning. She read all the books countless times, like for movies that do not get tired of seeing and reviewing. Anyway, she knows the saga on the fingertips. Well, imagine that through this book, she discovered information that was unknown to him, what magic, is it not? There are also a lot of reproduction that are a delight, especially that of the Marauder's map, she dreamed me she said to possess a day is done! .... .. To be honest, I found it a bit expensive and I was hesitant to buy it. But before the enthusiastic reaction of my daughter, I do not regret it. So I highly recommend of course to all the fans of the saga, but also to others, because I also watched and it is really exciting because it is very well done.
