"I had a conversation with my widely-read 16 year old niece about Ready Player One over the weekend. [...]
interesting to me, she said, “if it were really a kid’s book the main character would be saving the world by doing something spectacularly brave and personally edifying, but he only wants to save himself by getting rich which is a grown up plot and not very satisfying to me.” Her conclusion: it’s a dad’s book pretending to be a kid’s book." http://www.hbook.com/2011/09/blogs/read-roger/ready-player-one/
