Good luck with NaNo! I've never officially participated - well, one year I signed up but then didn't even start. Heh. But The Iron Witch was actually an unofficial NaNo novel from way back in 2007. That's how it started life, anyway. Obviously went through a ton of revisions, etc. later on, but me and a couple of friends just decided to do out own version of NaNoWriMo that year. We were aiming for 30K, but I ended up hitting 50K and really surprised myself.
Thanks for adding the book - I am proud of it because it's the first one I ever get published and I worked SO hard on it. But at the same time I see things now that I know I could do better. That's what keeps us writing and creating, though, I think: pushing forward in the hope that, perhaps one day, we'll match our vision of a project with the actual execution.
