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 didn't enjoy this book. It was too light and fluffy for me. I occasionally like chick lit but this wasn't well written. Each chapter ended before the main action was resolved and then it would be glossed over in the next chapter. I found that very frustrating. The characters weren't believable and I didn't enjoy the story line.
