What are you asking? My first poker book was by Ken Warren. Then I bought Lee Jones "Winning Low Limit Holdem", borrowed HEFAP, and bought SSHE. The most helpful was SSHE. That may be because I understood the game better, but I think it's just the best book for low limits.

If you've never read a poker book, unless you're a natural poker genius, any of these will help. That said, I still recommend SSHE over any of the others listed.
