Nancy Kress has both a novella and a short story on the list. She is a fantastic writer, so I will definitely want to check those out. I was very happy with her Beggars series (Beggars in Spain, Beggars and Choosers, Beggars Ride, all sometimes known also as the Sleepless trilogy).
I am happy the Harry Potter book is on the list. I think it was a well written and good book. And like giving Return of the King awards on behalf of the entire trilogy of films, I think it's appropriate to reward the final Harry Potter book on behalf of the entire series. Sci-Fi snobs aside, it was a fine series that had a significant impact on the field, and will be remember long after almost any other books of this generation.
