in the book "This Boys Life by Tobias Wolff, what is the diction, mood and sentence development?

The book is broken down into seven sections, each appropriately named to fit that particular phase in the main character's life. Each section is divided into short chapters. Most of the chapters are less than 10 pages. Each chapter discusses a particular event that shaped that time in the author's life.

The book opens with a section titled "Fortune." In this section, Toby and his mother are about to start a new life for themselves. The author creates an air of optimism that is quickly crushed. This is indicated in the next section title, "Uncool."

The shortest section in the novel is "A Whole New Deal." It includes one chapter about Toby's car ride with Dwight to Dwight's house. The length of this section has great significance. It's the shortest in the book because it has the most impact on Toby's life. The scene in the car is all that's needed to foreshadow the next five years of Toby's life.
