Bests & Worsts Reviews from Amazon

I received this free as the December Amazon offering. It appeared to be the least bad of the offered options, which is the only reason I selected it. All the books offered as free reads for several months now have been basically the same. Mediocre and formulaic. Mediocre writing, mediocre plot, mediocre characterizations, and basically manipulative and boring. Why is every offering from the same genre? Millennial snark meets gothic romance. Amazon, please widen the choices to include a greater variety of books. The past several months' offerings have just been garbage.
