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.
My daughter loved this latest book even better than the last! She did her school book report diorama on this and it was a huge hit! James Patterson and Steven Butler have doggone done it again! Their books are fun, funny, and keep kids interested. My daughter finished this in a day and was onto book 4. She loves them so much she re-reads them. I definitely would recommend for ages 7+.
