If you like this then you'll like The Catcher in The Rye. The Catcher in The Rye is about a boy named Holden Caulfield who has just been kicked out of yet another school and now must head home to his surely angry parents, but he decides that he'll spend the little bit of time he has left to have some fun (and even learn some very important things about life and about himself.)
