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.
Sorry to be the first not to wax lyrical about this book. I do realise it is for a younger audience but I felt there was very little story/substance to it. The book itself is of good quality and well illustrated.
