My friend Jean has a fancy real book club with live, face to face meetings and everything. She recommended this book.
Extremely Loud and Incredibly Close by Jonathan Foer. It was very creatively written from the viewpoint of a nine-year-old child who lost his father in the 9/11 tragedy. The kid was on a quest to find the lock to a key that he found in his father's closet after his death, so there is a bit of a mystery about it.
