Query: Dan, You let me down

Of course we know that Dan knows how to make us turn the pages really fast and furiously. That is great. This book, like the Davinci Code, drew me in. I got quickly caught up in the characters and plot. But when an ending goes flat and array like this one did, it is in some ways all the more dissappointing. I was expecting a wonderful wrap-up to this thrilling ride. It just didn't make it at the end.
