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, daughter loves it. I have to read it every night. Only reason it is 4 stars instead of 5, is because I didn't read the fine print and was shocked when it has stickers in it. Stickers and a (at the time) 2.5 year old are a bad mix lol.
