Dead to the World, by Charlaine Harris. Sookie book #4, my book #19:) Loved it. I am starting to remember why I like these books so much more than the show:)
From BN:
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 lifeBook Count : 19
