Of two minds

As some of you know, I'm currently drafting the sequel to The Heir's Choice. The weird thing about it is that I sorta think it's done.

But I'm not sure.

See, my rough drafts are done as soon as I feel I have enough information mapped out in my head to rewrite the whole thing to my computer. This rewritten draft will be the draft that I edit.

Unfortunately, the completion of my rough drafts always creep up on me. I can't say something like "Only five chapters to go and I'm done." Instead, I'll be writing along happily, only to realize that I don't have to write any more of the story. At least, not yet.

I've been getting a hunch for two days now that I'm at the end of this draft. And today, this hunch crystallized in my brain into "Yup. This is done."

Thing is, this happened much sooner than expected. Almost exactly 20k words in. Okay granted, this is the second time I rough drafted this story. So maybe my brain's feeling like I rehashed some stuff that I can use in the rewrite. Which means that yes, I probably do know everything I need to in order to write out the whole thing.

But therein lies the rub. Probably. 

I have a ton of aspects to the story left unexplored. I know they're there. I know that I haven't really figured out how everything fits together. Which means that there's a very real possibility that I might want to start rewriting early next year, only to discover that no, the story wasn't as done as I thought. Something like that happening could be catastrophic to my plans.

That said, my gut and my muse says that this is done. That I can turn what I have between the two drafts into a plot and (more importantly) a story.

But at the same time, I just can't help wondering if my muse doesn't want to move on just because she's working to a schedule.

Advice? Anyone?
