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.
So sympathetically presented, a story to encourage companionship between reader and listener as they find clues and are delighted by surprises. From 2 onwards, this book will be a long stayer on the bedside table.
