Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I loved the stories and how each ended with a HEA. However I still don't know what is the problem with their grandmother that was inferred a heck of a lot throughout the whole of the 3 books. So that did annoy me somewhat, enough that I would not buy the books about the other girls just to be led by the nose until finally somewhere, probably on the last girls book or maybe not if the author is planning something else, the big reveal may take place. Otherwise the books were a great read and almost standalones except for grandmothers reveal.
