On a personal note:
I confine most of my reading to fiction, with occasional forays into works of history, which may be a different type of fiction. Every once-in-a-while I look at non-fiction. Sometimes it is by accident. I find it amazing that I downloaded this Kindle Single on September 11. I did not preview the book. I believe I clicked on the icon by mistake. If I had known it was about the attack on the World Trade Center, I would not have downloaded it. For me, there is just too much noise and repetition of horrible personal tragedies. This book is not like that. It is uplifting and hopeful about survival. It was an emotional read for me and the best that I have read about coping with a huge disaster (the event itself) and personal long-lasting grief (I can save only myself).
