I assume it’s a parodic, non-copyright-infringing synonym of a certain “sparkly vampire” story that also contains at least one werewolf. The book has an apple on the cover, and I assume that’s supposed to be an apple on the spine of the book in this comic.

I’m a little afraid to ask, but what is “dusk?”

It’s gotta be either porn, one or more kinky mfers, or a reference to some weird story, like saying “MLP jar”.

I’m satisfied with this exact amount of information and no more than that.

Edit: Oh, it’s Twilight. So it was porn, just without the sex.
