Monday Quiz: Guess This Book

I had a lunch meeting in midtown Manhattan the other day, scheduled for 1:00 p.m. When I got out of the subway at Columbus Circle, I realized that I had about 20 minutes to kill. So I went into a Borders bookstore. I picked up a book on the front table, a new non-fiction book, and became so engrossed in the first chapter that I forgot everything and wound up being late to my lunch.

What book was it, you ask, that was so mesmerizing?
