Why I fight

I was reading this book called Why I Fight. I read the whole book and it is a story about a boy who burned his house down and him and his family went to live in and his uncle came to take him on the road with him. They stay at his uncles friends houses along the way and they train him to fight so they can have money to survive but he and his uncle start to grow apart and tensions rise on the road and he soon moves back with his mom and dad. I think it is a good book and it shows how hard it must be to live on the road with no home. I think the authors motivation to writing this book was to show people how tough it is not having a home and having to make a living with no real job.
