Update: I did order and receive Stephen Camp's Hi-Power book, and it came within a few days. It's quite informative and of very high quality. So, it would appear his wife (Sandy) is carrying on the business as before. Since she's listed as the "editor" of the book, I suspect she was handling this end of the business anyway.
