What werewolf novels do you recommend?

I asked a question similar to this about vampire novels. I read Blood and Chocolate and loved it but I like a little bit more mature reading along the lines of the southern vampire series (aka TrueBlood). I don’t mind sex scenes and all that but I would prefer recommendations that aren’t along the lines of Laurell K. Hamilton’s work (Anita Blake series, that kind of sex stuff is a little too much for me). I appreciate any input offered.
