Probably the best book I've read so far is Harrington on Hold-Em.
To read Sheriff Fatman's review, please click
Harrington on Hold-EmPersonally, I really enjoyed Greenstein's
Ace On The River. If you're looking for something a little bit different, then that may be the one for you.
You'll find links to amazon at the foot of both of these reviews.
Other books that spring to mind are Super System, Theory of Poker, & Book of Tells. I'd recommend all three.
Hope that helps.
