I think you told us before Paul, but I can't remember and didn't find it when I looked...
I this re-release of Black Wind an Author's Preferred Text?
FWIW, it seems to me that cover may do the book a disservice, as it implies that the 'Black Wind' is somehow related to a nuclear explosion. It struck me that way, so I asked a few folks who'd never heard of Black Wind what they thought, and got the reaction from all three of 'Somehow the bomb produces a black wind?'.
(BTW, for me finding folks I know who'd never heard of Black Wind was not a very easy task.)
