Query: Biased reviews

All of these reviews are from other authors of similar titles. They're all biased, friends, associates, paid, or all of the above. Irrelevant of content, this deserves a 1-star to balance out all the bogus ratings. Falsifying the merit of a book to create sales rather than relying upon genuine readers' opinion is morally wrong.
