As far as I know, there are no books that specifically focus on short-handed hold 'em games. However, there is a wealth of information on the internet if you were to google "short-handed hold 'em strategy" or something similar.

Is your game a ring game or tourney style? Depending on what kind of home game you play in, that changes possible suggestions as far as reading goes. Picking up a copy of Theory of Poker by David Skylansky never hurt anyone though.
