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.
I am an old hippie woman who likes books that have it all and stories that are written out of the box. Love the adventure, substance, girl power, history and the time travel element in this series. Thank you to Lisa, the author, for giving this wonderful story. Peace
