A new novel

Although I'm still toying with the YA novel I started, I broke ground on a new novel today, and this one certainly won't be YA.  Yes, I'm back to writing dystopic fiction.  The new novel is once again about an oppressive government and the struggles of the individual to not only survive amidst the oppression, but to actually attempt to overcome it.
I've had the idea for a while, and I even knew a little about the main character, but I wasn't entirely sure who he was until I wrote the first 1000 words of the novel today.  Now I have a much better idea of who he is, what he wants, and what he might be capable of, so now I can sit down and at least put a loose outline together, so that I don't get lost in the rest of the novel.
Life is still very hectic, and the "real" job is still wearing me out, so I have no idea how long it might take me to write this book, but I'm pretty excited about it, so I'm hoping it will flow quickly.
