I've been editing novel and working with established storylines for so long, that it felt positively refreshing to write the beginnings to not one, but two new stories today. Got about 800 words on each. And on the second story, another large chunk of plot fell in place, one that's perfectly tragically horrible, but it explains all sorts of things I had planned for later in the story, but couldn't figure out exactly how to get there. Now, I know. It will not make readers happy, it doesn't make me happy, but of course, it all delights me no end anyway.
