Read this excerpt from Extremely Loud and Incredibly Close.It took me nine hours to make, and I had thought about giving it to Sonny, the homeless person who I sometimes see standing outside the Alliance Française, because he puts me in heavy boots, or maybe to Lindy, the neat old woman who volunteers to give tours at the Museum of Natural History, so I could be something special to her, or even just to someone in a wheelchair.
