Novels have power to change reader`s opinion about the topic in the novels. The book "About a Boy" deals with a variety of topics such as single mom, loneliness, suicide, friendship, and so on. I read this book and changed the way I look at the world. Among them, the point of view of loneliness and love has changed a great deal. Maybe I had never seriously worried about loneliness and love before reading this book. I read the book “About A Boy” and then I want to introduce my changed viewpoint.
