Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
In book 2, the author really gets extreme with the sex acts that Mark...and others...put Casey through. Certainly not a book for the faint-hearted. Although wife-sharing is my favorite topic, this goes a bit too far for my tastes.
