Amazon calculates a product's star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers and factors that establish reviewer trustworthiness.
The author has really crafted beautifully. What invited me was the cover page. I was flabbergasted when I saw those beautiful designs and drawings which were justifying the poems. Really appreciate the innovative idea.
Most of the time I was lost in those drawings thinking that the author could be a good artist too. Few of them were so pleasing that I took screenshots and made them my phone wallpaper.☺️
