Bests & Worsts Reviews from Amazon

I loved the book. Really. Initially I posted 5 stars. Changed after failing to locate the sequel in the Kindle store and concluding that a sequel has been published not through Amazon Kindle but only through a site (Patreon) that requires a monthly subscription. No objections whatsoever to the great work of Patreon. It is however totally unacceptable to lure customers/readers into such a sham and quite unbelievable that Amazon does not restrict such tricks.
