The fifth episode was a turning point in the atmosphere. The world was at war and the characters suffered. The atmosphere was dark and heavy. This sixth volume continues to increase the pressure, but instead of having a linear progression, it is sawtooth. Moments down the curve used to Rowling to develop the psychology of his characters. We discover them other facets. We can blame him for sure to linger on too obvious facets, but overall from the first to the last page, it's a wonder, despite an obvious outcome. The author reserves and more sacred opportunities for the conclusion of his work ... a beautiful book. Harry Potter is definitely no longer a children's book. It is quite far from the first tom.
