I don't remember when or how this idea popped in my head—it might have been on the road? I don't remember, anymore.
I've been waiting to write this book and to motivate me, I sketched this out a month ago, but every time I gave it some thought, the story got more and more complicated. After figuring out a good jumping-off point to begin the outline stage, I finally got around the painting it in.
"Noah in space" isn't the title, just the elevator pitch, and I'm sure it'll be my next big, long-term project.
