Writing Urge

So I've had this massive urge for a few years now to write a young adult dark-fairytale novella. Kinda like LJ Smith, minus the schmoop factor. I wrote a short story based on the tale of Tam Lin, and it is time to make it into much more. Problem is, I'm no time girl, and overhauling it will mean *months* of working and then finding a beta reader who doesn't mind if it's not fanfic.
So I'm setting a deadline. October. October 31st, the damn thing will be mostly done.
Because it might be the blaring Loreena McKennit, and it might be tomorrow's full moon, and it might be the pull of Beltane, but the story is yelling at me, saying "Dammit, pay attention!"
So, ummhmmm. I'll be fairly fairy-centric in the next few months.
