Extremely Loud and Incredibly Close

I’m talking about the book Extremely Loud & Incredibly Close by Jonathan Safran Foer, and the 2011 movie adaptation. The story is about a boy named Oskar Schell and how he’s dealing with the loss of his father, Thomas, who was at the World Trade Center on 9/11. About a year after his father’s passing, Oskar finds a mysterious key in his dad’s possessions, and he goes on a quest to find what the key opens.
