I even made a cover of sorts. I still have a couple of days to figure out the rest of my plot. I'm deliberately not driving myself crazy trying to follow all the plot templates at once, this time, or even worrying too much about whether my viewpoint character is a sufficiently proactive protagonist; I just want to be writing again, after a hiatus of more than a year.
I dunno how I managed to paste the image in twice instead of the credits. Trying again, with apologies to those concerned!)
