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.
