I've been researching my little brains out, and that's always a great way for me to get ideas. I can see the broader structure of the thing and have that written down. Three characters have come alive in my head, and this last one told me he was the one to start with. I got an opening scene of 420 words written, all action and dialog, and it was dead easy. Felt like it all happened in about the time it took me to breathe twice. Please, oh please, muse, give me more days like this.
