I'm revving up to try my hand at NaNo agian this year. I didn't "win" last year (http://iwroteabook.blogspot.com/2010/10/nanowrimo-and-bliss-of-delusional.html), but I had a great time, met my current writing group, and wrote many more words than I would have if I'd just spent November the way I spent September and October.
I had hoped to be completely done editing Power Trio (Book 1) before starting into Book 2, but the plot is pretty set, so I don't think there will be any major problems. I've also heard that you shouldn't start "Book 2" until you've sold Book 1. I can see the logic- obviously you don't want to spend a ton of time on a series that will never be published, but I'm so attached to the story and the characters I don't think I could not finish it.
How's that for great English? Reminds me of one of my favorite quotes from Scott Pilgrim: "Double negative... it's tricky."
Anyway, I'm feeling good this year. I might take a little time tomorrow and do a quick outline, so if I get stuck, I'll know where to head. Wish me long, and forgive me if I'm around even less frequently. I have to save all of my amazing wit for those ~1,600 words a day! Ha!
