The book im reading!!

The book I am reading is called The Cheat. Its about some friends at school had a exam in class and a couple people tried to look for the answers from last years exam so they can cheat on their tests. Of course it didn't work. The teacher that was grading the exam and he saw that only a couple people had the same wrong answers so he called the principle and called all of them down to the office. After school was out something weired happened to bobby. He just disappeared. So he was gone all night he was so scared to go home to his mother and father and tell them that he cheated on his exam. He was eating out of trash cans living like a bum. He saw this man drop food and a drink in a trash can. He looked around and went for it.. But he shouldn't have done that. Two cops came up and asked him what he was doing and he was caught right there. I like in the book that the author wrote their names on each page of the person who is talking next. I don't really know if this book will pull it together so I can understand the book and what its trying to say.
