I know I'm late to the party on this one, but I did read The DaVinci Code when it first came out (which this book tries to pattern itself after) and somehow never heard of this one until now. Khoury has crafted an intriguing story that once again casts the Vatican as the antagonist, and connects some of the same dots as Dan Brown's thriller. It's fast-paced, and leads to a satisfying conclusion. However, I do have to mention that a few of the references to the aftermath of 9/11 feel a little dated now. Also, I think he would have benefitted from a technical editor in places (the business end of a gun is called the barrel, not a nozzle, for instance). But overall, if you enjoy stories about the mythos of the Templars (I'm looking mostly at the audience of The Curse of Oak Island), you should give this one a read.
