I found this service from a writer friend's Face Book post now over a year ago, paid for some initial help in editing my blurb and creating a sub-title, then Amazon, Pinterest, and Face Book ads. At every step, the cost was very fair (and far less than the typical author marketing services), The communications have always been to the point and fast. Most of all, my sales have been remarkable and from many regions. I had only my own hand-to-hand sales to relatives and friends before. Excellent reviews of my work keep piling in on several Amazon regional sites, Good Reads, Smashwords, and Kobo. The book we have been working on together has even made some honest best-seller lists. I don't hesitate to recommend this group to any author. In my experience Books Go Social will not take on a project unless it believes it can help. This is not a "we'll take you money and give it a try" business.
