This book shows everything that has been and everything that will be. But it ony shows you the things that you are interested in. if you where a girl you might see stories of princesses and knights and love stories. If you were a boy you might see stories of sports or battles or bank robberies. It also changed as you got older. Showing you things you really want to see. I mean it is the book of everything and there are lots of things that are just down right boring.
