I like the idea a lot. I would have two concerns, though. Possibly just because of my being in the 150-300 years old demographic...
First is the profanity. I like a good bout of swearing as much as the next guy, but it also tends to turn me off a bit when there's absolutely no purpose to it. I think in this case it's a bit distracting because the ad's so minimal that the pointless profanity is almost all there is to it.
Second is what I just said. This is a great gimmick, but it's
so gimmicky I'd be worried it's just as easy to skim past as it is to scan it.

(Granted, I just showed it to my lovely lady and she thought it was pretty intriguing.)
I'd at least put the title. I know it kills the minimalist nature of it a bit, but
Pavlov's Dogs is such an awesome title, and with werewolfnovel.com it gives people something to latch onto if they don't scan it right this minute.
