When I have the time for it, I've decided on the next book I'll write. It won't be occult-focused. Instead, it's going to be about Christianity, and written for the Christian audience. They're always buying "How to be a good christian man" books for each other, but they're all written by pastors towing the fundy line.
I'm going to write one for the rest of us Christians. You Don't Have to be a Dick to be a Christian is the working title for now. I think it will make a difference.
