As someone who adopted New York as my home just two years before 9/11 -- and who watched the first tower fall with his own eyes -- I debated whether to create this book list. In the end though it deserves coverage like any other topic; ignoring it won't make it go away. I think that no matter your literal or emotional distance from Ground Zero on September 11, 2001 there's at least one book on this list for you.
Finally, while in my opinion these are some of the best books about 9/11, I'm sure there are dozens of excellent titles I've missed. If you know of any, drop by Flashlight Worthy and let me know what I've missed.
