All authors know that getting reviews is probably one of the better was to get your stories noticed. Honest reviews are always best folks. Purchasing those reviews is not a good idea. But there are services out there that may be a good investment such as Goodreads, Net Galley, Bookbub, and even Book Funnel. Each has their own costs, requirements, virtues and not so great problems. Netgalley has curated books by traditional publishing companies that offer previews of upcoming books to those who are willing to read them, provide a review and some feedback. I just join last month. I had heard through the internet grapevine that they even send out paperbacks and hardbacks to the more prolific reviewers. I am going to give it a go for a year and see what happens.
