If you do a search on the forum for the previous discussion on this, I read that Sklansky and Miller's brand new book is supposed to be really good for NL cash games.
Sklansky/Miller's "No Limit Theory & Practice" is ground breaking IMO. I think it does for NL what Theory of Poker, and Super System did for poker. It's an amazing book with so many thought provoking ideas. Many of which we already do, but find it hard to explain why it's correct.

I'm looking forward to Negreanu's upcoming 'bible'.
