I love the nonfiction picture book Nic Bishop's Frogs selection of course...in fact used it in a catalog class situation last week. It is a perfect example of why kids can't get enough visually-stimulating science books! Here is a podcast with the author of the winning book from the Just One More Book site!
The only other winner I am familiar with enough to even mention knowing is the haunting, somewhat disturbing, YA novel Hunger Games. So much to think about on many levels.
