To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Brilliant. Great books. I've read all the Mitch Rapp books and the Mark Greaney Gray Man series is equally as good. I've read five of the eight so far and loved them. Don't forget the Tom Clancy books written by Mark Greaney.
