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 11 year old son is sports obsessed. It is easiest to get him to read sports related books. He has read the whole series of these and loves them all. After finishing the last one he said they need to write more of them. :)
My son loves this series. He's almost finished with it though and he's already sad about not having more to read! There are some pretty cute jokes in the book that the main characters tell and he always reads those to me!
