2nd edition. Believe its an update. I ordered it some time ago. Was told it would be awhile. Just got notice that its on its way. I posted some synopsis found recently from a threads. Very detailed on where he stands. Could only see a couple of incidence that needed adjusting. I’ll go find link if you want
I have a Nook reader and almost downloaded the book just before I asked the question here. Then it occurred to me that if it’s updated the new edition won’t be released until next week. I think I’ll buy the print version instead of the Nook download, so I can share it with others.
