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.
Loved this book! I am looking forward to reading the next one and I'm hoping there will be a whole series like this. I will be looking out for more books by this Author. It's an amazing achievement for a young man with Autism!
