Just finished Midnight's Children, which might be the best book I've ever read. Seriously, read it NOW.
Picking up The Giver, by Lois Lowry. I read it back in 4th grade, shortly after it first came out. I was already an avid reader, but I think it was the first book I ever read that got me thinking about ideas and issues bigger than the specific events of the stories; it was also my introduction to the idea of dystopia.
I decided to pick it back up for two reasons. First, I'm working with kids right now, and I constantly recommend this book. I realized that I remember how the book affected me a lot better than I remember the book itself. Second, I just found out that it has two sequels, and I want to check them out.
