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 analyzes reviews to verify trustworthiness.
The book itself as far as reading was good, but, I ordered a new book, it was a Christmas gift for my three year old grandson and the left upper corner had gotten crushed somehow. I was disappointed in that aspect.
