"The Grid - The Cost Of Humanity Book 2" The Price Of Feedback

Not to many weeks from now I will be publishing "The Grid - The Cost of Humanity Book 2". It is the sequel to "Still With Eyes Closed". To date I have moved a total of 4,000 books. Through sales, Kindle lending, and promotions. Very few have taken the time to remember to leave feedback on Amazon. I asked Amazon for suggestions, from their experience those who really enjoy a book seldom remember to leave feedback. Haters seem to remember. All 3 of my books are currently getting 4 & 5 stars, but few have taken the time to do so.
When I released my first 3 books I hand gave away many signed copies, those who freely took a copy promised to leave feedback. Some have, all the others gave me a verbal 5 star rating and promised to leave the same on Amazon, few have kept that promise.
Authors need good, descriptive, thoughtful high star rating feedback to encourage others to purchase the book. With that in mind with the release of "The Grid" I have chosen to keep it as a purchase only. Ones who followed through on my other books did so for those books. I am hoping that in the end honesty plays out and my work is worth buying.
