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.
I enjoyed this a lot more than the first because it's not stop action from start to finish. Apart from an interesting side story this is a military sci-fi novel complete with high tech gear. Will buy the next.
