Two interesting points:
- The idea of a transformation that occurs at the result of an uncontrollable emotion. (Certainly as a teen, I too might have been called beastly by mom.)
- The consequences of that change: unintentionally hurting those around you. Also, part of the teen experience for many.
I'll add to the list this: Immortality. My teenage years were filled with scary, stupid, reckless decisions. I never thought I was immortal, but the issue of mortality just didn't apply to me yet. Did I want to be immortal? Sure. Why not. Bring it on. More time to finish my homework. I think that being absorbed in a story that has to potential to go on forever is highly attractive, not just to teens.
Later, I asked Richelle Mead what her thoughts on the future of these immortal beings may be. It's her belief that the way in which the creatures are presented to readers will shift, but still remain popular. I'd go along with that. I'd also say that all things wax and wane and while we are in a period where this is it, all things find their turn at the bottom of the wheel. Eventually, that is. Rome had a pretty long run.
Will it happen soon? "Our list isn't indicating it will," say on of Big 5's publicity professional.
There you have it, folks.
