Volume 4 is (in my opinion) one of the best of the cycle, it is particularly difficult for it to ensure continuity. One can not help but be a little disappointed. Yet the story continues, and the author develops his characters any great way. Depending on your preference, you're going to love some and hate others, but none will leave you indifferent.
Some big events must make this volume, while pushing us to wait and forward. In short, it is always as strong and addictive.
