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.
Very enjoyable book, am slowly but surely coming to the end of this series of books, must have started about 10 years ago! Didn't give it 5 stars as some parts of the story were very slow to develop and his style of writing can rub you up the wrong way if you are a bit restless while reading. All in all a good contribution to a fantastic story!
