Query: You're Kidding!

How is this book different from Da Vinci Code? Not very much, except that it is a much inferior read, and makes much less sense. The author seems to have written these two books in cookie-cutter style, with an unsuspecting protagonist, the close-of-kin lovely, a completely implausible plot, all rotating about an ancient sect that no one knew existed in today's world. It was a fast read, but a very poor one.
