I liked the first part of book. The author has done a fine job of portraying the room through eyes of Jack. But Emma failed miserably to bring out the emotions & trauma one will have when they are re-entering the WORLD after 7 years. In case of Jack, he is seeing the real world for first time.In the second part, I felt Jack was talking too much for his age, keeping the aside fact that he was confined to a room all those years.
