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 had the same issue as the previous reviewer. I purchased thinking that I was getting the first volume (as it said that this book was 128 pages) and I was disappointed when it was just the first issue. I enjoyed the book itself but don't want to by another issue! This review does not reflect the book itself but the fact that I was misled by amazon.
