Have still not sold many copies of Penance without advertising. So...I'm dropping the price on Amazon to .99. We'll see if that generates any sales. Again: no advertising for it. I'm just waiting to see if anything clicks.
In another month I'll upload Vengeance, probably priced at .99. Then a month or two later I'll upload Compassion.
I'm so busy with other things this summer that I'll probably just let them sit there for a while before I purchase ad space. Or maybe I'll buy an ad or two once two books are there.
I'll update you on results!
