I don't understand why you don't treat each chapter as a book in itself? When a book really interests me it gets a rapid read with the addition of treating each chapter as a book in itself. I did this during my PhotoReading seminar on the weekend. During the students activation assignments. I did what I needed to do for the lessons and then spent the remaining 3 to 7 minutes activating a chapter. All told I finished the book in 40 minutes including 6 pages of my own notes and ideas expanding on what I learned.
