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 have read Bijou books before and really enjoyed their dark side. This book was horrific and I honestly am struggling with how the other good reviews came about. This was a juvenile storyline at best and I had to force myself to read the entire book. Don't waste your money
