And the books given away aren't generating reviews. Since the point of the giveaway is to get the books into the hands of people to read and review, the lack of reviews means no return on investment for us.
Small publishers (like HWB) and independent authors are dependent on ratings and reviews posted on sites like Amazon and Goodreads. If you read our work, we really do need you to rate and review it. We need you to tell your friends and family about it. That's how word about our work spreads and enables us to continue writing and publishing.
