I would set it as a free book forever if I could - I'm not concerned with taking your money - but Amazon won't let me. So grab it through here while you still can. Even if it's not exactly your genre. It's still free stuff. Tell all your friends too. Maybe it is their genre.
Now I just wish there was an easy way to inform all those 1100+ people who have my book as to-read... maybe I'll private message each of them, individually, about it?
