“ To the jaded eye, all vampires seem alike, but they are wonderful in their versatility. Some come to life in moonlight, others are killed by the sun, some pierce with their eyes, others with fangs, some are reactionary, others are rebels, but all are disturbingly close to the mortals they prey on. I can think of no other monsters who are so receptive. Vampires are neither inhuman nor nonhuman nor all-too-human, they are simply more alive than they should be. ”
