Ring Games - Any good books out there?

I'm a decent tournament and SnG player who can place ITM about 65% of the time, however I almost always lose my winnings in ring games. Can anyone recommend any good books that will help me adjust to ring games? I've got HOH and Sklansky's Tournament book, but obviously neither of these will help for ring games. Thanks.

NLHE Theory & Practice/Sklansky is geared to cash games.

NLT&P is great if you are looking to really advance your cash game and play some very high level poker...but i dont really recomend that you read that book until you are already a winning player. a better book to start out with might be phil gordon's little green book, which is helpfull for both ring and tourney.
