Thanks for the info on your book. I just found your post and am looking forward to seeing what you did in writing your book.
I've also just gotten the chance to see some family letters from WWII, and I'm transcribing them on my blog. Although mine aren't from as exciting a tour of duty as your father's (my father in law, Francis X. Stevens, served in the Navy on an LCI, present at Iwo Jima and Okinawa), it was an eye opener to see a first hand account (minus the censor's clippings) of someone near the front lines in these historic battles.
It seems that letters like this need to get out there where others can see them and think about it. There aren't too many of these veterans around anymore to tell their own stories. Someone ought to be passing them along.
I'd like to know more about your thoughts on writing your book and the response you've gotten to your work with these letters.
