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 this book. I rarely write reviews but I read the first book and this one in three nights and found them both to be gripping stories that really had me guessing the whole time. If you love a good mystery, give this series a try. The main character was an fbi profiler who's world has turned upside after a divorce, she is a mum with mum probems who is very real and likable character, who makes a hell of a good detective. I really could not have guess the plot twists in this series.
