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.
Great book. Great author. Can't wait for the next one. Encouraged my 8-9yr old to read more. He really liked the story. He has read all of the Kid Spy books by Mac B. Recommended to his friends and they started reading the series as well and had great reviews.
