Extremely Loud and Incredibly Close

I have just finished reading Extremely Loud and Incredibly Close by Jonathan Safran Foer. Overall, I really enjoyed the book. Basically, it was about a boy named Oscar Schell who journeyed around New York City looking for the lock to a key that he had found. After his dad died in 9/11, he thought that his dad had left him this one last message. Besides this main plot, the story, through a series of letters, explains the life stories of Oscar's grandparents, a story that is moving enough to make a book out of itself. This book was more of a mystery than anything, because a lot of confusing and seemingly disconnected stories are revealed at the beginning, and then through small bits of information scattered throughout the story, everything comes together in the end. I thoroughly enjoyed trying to figure out the puzzle, and predicting what would come next. (although I was always wrong).
The story of Oscar is heartbreaking, and the one of his grandmother and grandfather even more so. This book revealed the hidden story in everybody's family, and carried an inspirational theme throughout. Especially the ending really got me thinking, as it did not wrap everything up as neatly as I thought it would. The best way to describe it would be as a sad "happily-ever-after." I highly recommend this book to anyone who wants a moving, inspirational mystery told through the unique perspective of a young boy.
