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 daughters absolutely love the Emily Windsnap books. They were not sure how much they would like them when I ordered the first one, but both the ten year old and the 13 year old have really enjoyed this series.
We love Liz Kessler. All of her books are great and inspire reading. The Emily Windsnap books are fun and adventurous; I just wish she would leave some of her remarks about not believing in God out of them. I skip those when reading out loud to the kiddos; as it really isn't an children's authors job to influence my kids beliefs. That being said it is like one to two comments a book so take it with a grain of salt.
