comment on structure

The book is divided into three parts that represent the beginning, middle, and end of the story line. They are titled to mimic the parts of the day: Dawn, Dusk, and Night. Each part is further divided into chapters that are titled by number only. Chapters 1-3 appear in the first part, Dawn. Dusk contains Chapters 4-6. The final three chapters are in the third part, Night. The titles of the parts are indications of what aspects of the story line will appear in each part, but do not prompt ideas about specifics. The chapters are identified by number only, meaning they do not offer clues.
