Query: I thought the problem was me

I finished the book and couldn't understand how the pieces fit together. So I re-read the book carefully to attempt to make some sense out of it. Guess what. The pieces don't add up. This is especially disappointing since the book is a page turner. The problem only comes when you've turned the last page and realize that you've been "had."
