Actually, after he read my book on diving the ARIZONA, he contacted me and bounced a few ideas off on that particular subject. When I read Shadow Divers, I wasn't on board with the original proposed theory on how U-869 went down. There were just too many inconsistancies between the theory and the conditions of and around the wreck.
And as far as your statement goes, it should be "Life is an excuse to buy books".
I love books; not just because i'm a writer, but I love the 'hold it in your hands' format. It's not just the information . . . it goes far beyond that.
I can't seem to find who originally said it, but I've always liked the quote;
"If you would be right, read."
"Why do I do this? Because the money's good, the scenery changes and they let me use explosives, okay?"
