Take a look at this snap of the Teen section at the good ol' B&N and tell me if you see what I see.
I see a metric ton of red, black, and purple. A good assortment of chillingly beautiful, yet otherworldly faces. And confirmation that vampires aren't just a thing in teen fiction anymore; they're The Thing.
This, my friends, is the power of marketing, and of storytelling. Between them, Stephanie Meyer and her publisher have moved an entire generation. I predict we'll be seeing ripples of this effect in adult fiction for years to come.
