If you play NL cash:

Super System 2

Pot Limit and no Limit Poker

If you are quite new to the game, then Getting Started In Hold'em would be a good place to begin.

If you play tournaments:

Harrington on Hold'em 1 and 2

The Little Green Book of Poker- Phil Gordon

A couple of quick notes.

1. The chapter in Super System will have to be adjusted a bit to have success at lower levels.

2. Although the book Pot Limit and No Limit Poker isn't purely dedicated to Hold'em (other games included) it is currently among the best right now for cash games.

3. Although Harrington on Hold'em is for tournament play, much of the advice can be carried forward to cash game play.
