Dead to World (Southern Vampire Mysteries v: 4)

When cocktail waitress Sookie Stackhouse sees a naked man on the side of the road, she doesn't just drive on by. Turns out the poor thing hasn't a clue who he is, but Sookie does. It's Eric the vampire—but now he's a kinder, gentler Eric. And a scared Eric, because whoever took his memory now wants his life.
