Ultimately, I didn't like this book, but I hate failing any work with just one star, and parts of the plot were exciting, so I'll be magnaminous and give this two stars. I do enjoy historical studies, and have long been interested in the Knights Templar. When the opening few pages of this book were described to me by someone who had just started it, I mistakenly thought the book would involve time travel, and that intriguing overlay led me to eventually check it out for myself.
Those opening few pages were exciting, indeed. However, I also quickly noticed that the writing style was sketchy, the chapters short and not so sweet, and rather than offering the reader well chosen details and telling facts as evidence to arrive at conclusions about what characters were feeling or thinking, the author simply summarized, and the exposition was worked into dialogues in a very amateur manner. I thought I was reading a screenplay rather than a novel, only I lacked the benefit of an actor's depth giving any nuance or ambiguity to cliche behaviors and descriptions.
The obvious target audience is Da Vinci Code fans. This is a major rip-off of that novel in overall plot construction and flow, and it lacks even the less than stellar level of sophistication and adventure in the Dan Brown bestseller. (It does, however, take into account how post 9/11 security measures would affect conspiracy investigations, and it also pays homage to the popularity of "Finding Nemo.") The romantic thread between the hero and the heroine is sometimes hard to believe, as they both seem willing to change their entire code of behavior/belief system/worldview from time to time, rather abruptly, and illogically, because of the power of their mutual attraction.
Most of "the Last Templar" turns on a debate over whether Christianity (as it is understood and practiced today) is a charade knowingly propagated by the Vatican. If you are interested in a literary work (beyond the Dan Brown books) that explores such a possibility in a more compelling, thoughtful, and aesthetically pleasing way, don't read this, look to the Golden Compass series by Pullman.
The book lectures about Gnosticism as if no one ever heard of the Dead Sea Scrolls before, and explains overlays in the three Abrahamic religions as if connections between Judaism, Christianity, and Islam were a breaking news alert. Sure some of the adventure/action sequences in exotic locations kept me reading, but I think this story would definitely work better on the screen (and at that, probably as a TV movie on the Lifetime network).
Do I plan to seek out more books by this author? No. But am I still open to the possibility of other novels addressing this topic area or these themes in a more engaging literary and philosophical fashion? Yes.
