That, plus 200 extra pages of "the history of the gun culture in America." That was only going to be popular with serious shootists. Again, it kept it from a wider audience. Too much gun lore to wade through on the way to the story, it belonged in a separate book.
That's why I start on page one with the full-speed action. And that's also why (personal taste aside) I don't have any explicit sex in Enemies. There's romance that's very sexy, but not sexual. I see no reason to explicitly describe sex, we all know how it works! The sexy part is the "buildup," but when they get nekkid, I close the bedroom door so to speak.
I see it as the difference between "From Here to Eternity," (very sexy) and "Debbie Does The Gun Show" (UC: overtly sexual.)
Enemies is a very sexy book at times, but it's a book I would not be ashamed to have a preacher or mother read.
