I picked this up on the sale rack, and read it over the last week while traveling for work. I was actually really impressed by the book - well written, and for some reason the characters really worked for me. They were well-drawn and seemed completely believable. It was very interesting watching an essentially parallel spin on what Steve Berry did in The Templar Legacy. I probably liked that book better, but think this is a better book, if that makes any sense.
I won't give away the plot, but I thought it was a really good one - including the twists.
