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 persevered with this book, though halfway through felt it was extremely boring. The plot was predictable, and I get tired of reading about emotional women , with tears sliding down their cheeks, as they push a lock of hair behind their ear. I don't know if the recipes were inserted to make the book more appealing, but they didn't work for me.
