Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
This book is good because when it looks like the leprechauns were stolen by Lucky but then the kids found them in a closet in the police station. I think this book is a good book for March. I recommend this book to anybody who has read most of the books in the series.
