I loved this book he read in one sitting. The story is well done and to the last chapter we still hesitate on the end. The book evokes the perspective of three ways diary with dates. From time to time, even when you go back to see who speaks in chapter one is reading because the stories overlap. Nevertheless, this book is easy to follow and makes us want to continue to know what will happen afterwards. No wonder Steven Spielberg has already planned a film adaptation, do not hesitate to buy it.
