I haven't read the newer Kathy Reichs ones yet but have always enjoyed them, HO. They certainly fly off the shelves at the store!
The "me-too" books I can recall off of the top of my head are:
The Templar Legacy by Steve Berry
First Impressions by Jeffery Archer
The DaVinci Legacy by Lewis Perdue
I know that there are more, these are just the ones I can think of. Brad Meltzer's latest in PB looks to be about Freemasonry, as well-it's called The Book Of Fate.
I started to read The Templar Legacy and then realized that there are 3 other books with the same lead character first, so I'm going to go back and read them first. The Amber Room and the Romanov something are two of them, I think.
