Writing my tail off!

But I've got to admit, I'm not writing an erotic romance. It's not even a romance, to be completely truthful. It's a science fiction story. Really. I know you're surprised, maybe even shocked, but I had an idea that just wouldn't go away. So, I'm writing. And writing. And writing.

And loving every minute of it!

Anybody out there read science fiction? Have any advice for worldbuilding? I'm all ears!
