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 love the way this book is written like a story, it's easy to read and it covers topics I have always wanted to know more about. It is a beautiful book and the colourful illustrations bring history to life.
