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.
This is an example of a book that has totally lost its purpose. This author tries to tell too many stories, takes too many asides and if this was properly edited it would be about 110 pages. I was shocked. Save your time for better reads.
