The book was fiction, and to be honest I found most of the "puzzles" so obvious that I had them figured out 4 pages before the characters did. And no, I did not sleep at a Holiday Inn Express while reading it.
Actually the book was interesting except for the last 100 pages or so. The ending was subpar and disappointing.
I know it's too much to expect people to read the entire article before posting, but could you at least read the 1st paragraph? The review is of a book called Breaking the Da Vinci Code by Darrell Bock.
