If you could read only 1 published source, not this thread, for info on No-limit cash games what would it be. Remember - only 1 so you decide what the parameters are. ie. theory, practice, entertainment, etc. Just tell us why you made the choice that you did.
Mine would be Pot Limit and No-limit Poker by Ciaffone for the way it covers both the theory of big-bet poker and the practical aspects of how to play specific situations.
