If you liked GRRM's vampires, I think you're going to love those of Peter Watts. In his SF novel Blindsight, he tries to give a scientific rationale for vampires, including the bit about possible overpopulation. (They don't figure very heavily in the book, though; only one minor character is a vampire.) And in the spirit of the PDF discussion: Peter Watts' books can be read for free on his own website. (Although I still went out and bought a copy because I like to hold an actual book and to financially support the author.)
