This book was very poorly written and very confusing - Way too many characters with not enough character build up - and some things were introduced that there was no follow through on. Found several misspellings, or incorrect words, like it should have been 'had' and it had 'hand' - really hard to follow, and I read alot of these types of books.

If you're really into the fine details of codes and conspiracies, you'll love this book. I think it was too much work. It took until page 90 to finally find a character who you followed for more than one chapter. I went online to find book club questions and discovered that on forums the author was posting positive reviews of his own book. He also had multiple aliases in the forums and other participants pointed this out. They felt that he was trying to 'pad' the buzz about his book.
