If there is one thing in the publishing industry that it's importance can never be reiterated enough, it's book reviews. Think of that this way, have you ever bought a novel that didn't have a decent number of reviews and predominately 5 star rating? I can tell you on a personal level that I haven't and I believe that the majority of you haven't either. Our brains are unfortunately trained to sift for the good stuff based on the opinion of the majority. There is so much content out there, that we could never read it all. So our brain tells us, why even waste your precious time on an underrated/non-rated book.
