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.
Thank you for offering this book in italian. We purchased as a gift for italian friends and they loved it. We also purchased in Italian: Green Eggs and Ham (Prociutto), the Rainbow Fish, and a few more.
