What keeps me interested in the book

The book uses some decent vocabulary. He gives some good detail and makes u feel and wonder how it was to be young in the early 1900's. I also Like how at the beginning of the chapter he tells about the current situation hes in then he starts to remember a earlier part of his life. The way he writes the beginnings of the chapter at times doesn't tell much but at times it really gets you interested in the book. He also gets you knowing the characters pretty well.
