After refreshing web pages constantly, and even once refreshing the Pulitzer website when it already said 2009 on it only to find that that page was no longer loading fast at all, I have the winner:
Elizabeth Strout: Olive Kitteridge. I have not read it yet, but here is a page I created when it was a finalist for the NBCC. Please stop by there to share your thoughts! (link broken because I have now read it and reviewed it here)
Finalists: The Plague of Doves by Louise Erdrich and All Souls by Christine Schutt.
