Extremely Loud and Incredibly Close

I am starting Extremely Loud and Incredibly Close by Jonathan Saffron Foer today. I have no idea what this book is about. I just know that I loved his book Everything is Illuminated. And that there is a movie out about this book. Levi asked me to get it from the library, but they didn't have it, so I had to do an inter library loan. I'm hoping we can go see the movie after we both finish the book. :)
