Almost as soon as I made the previous post, things started to come together. I've now got the gist of a story worked out.
My goal, once I finalize the outline and start writing the actual novel, is to crank out the first draft in six weeks or less. It won't be easy, but I think I can do it. Anyway, it's a goal to shoot for.
I also need to start playing around with Blender. If I'm ever going to use it to make images for book covers, then I'll need an idea of what I'm doing.
