Mockingjay  - Suzanne  Collins
This one is going to stick with me for a good long while. Difficult and heartbreaking but real. Mockingjay (and the other books in the trilogy) do not pull any punches even though they are for a YA audience. In a lot of ways, the books remind me of the new Battlestar Galactica show. Wish I could speak more eloquently than that but I'm still chewing things over.
