Quite a big one, as it's turning out. I started the outline back in May and it's finally coming to a close. The outline has ended up being about forty pages longer (the outline, yes) than I was anticipating....so there's no way that a) I can finish the outline and b) finish the looking-to-be-a-lot-more-than-50k words book this month hah. But I'm definitely planning on it next year, provided I haven't overloaded myself with another giant novel in the meantime. Good luck though, I'm sure any of those ideas will be a ton of fun!
