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.
Wow! Andy Hunt’s sequel, Conglammora Found, is excellent. The writing and composition is many levels up from the first novel. The first book was largely single-threaded, but the follow-up makes use of a multithreaded narrative to keep the reader engaged. The book ends very open-ended and the groundwork is in place for several more stories in the Conglammora universe.
