Not to make your decisions harder, but here's another possible for the Nano book:
The Sad Tale of Horace VonFinkle, Villain Very-Not-Extraordinaire
I really don't identify with Horace much. After all, he is a villain. He just can't seem to do villainy effectively. Every time he tries, things turn out well. Sort of an opposite of Eleanor Blunt. She's still the front-runner (those two votes really turned the tide) since I have been thinking about her journey for awhile. Richard Peck says you need to decide on a journey, and then decide which character will benefit the most from it. Eleanor's journey is to discover that one's worth is not determined by one's perfection.
