Take a look at Coach Heisman's recommendations:

You could also do a "search forums" for oh, maybe, best book for amateurs:
http://www.chess.com/forum/search?keyword=best+book+for+amateurs
A search for "best beginner's book" would probably return better posts, but I'll leave that to you.
I thought of ordering "my system" by nimzovich, but before I do that I want to get your opinions. I'm still an amateur but I have decided to take chess seriously, I want to make myself proud:-). So what do you think about this book and I read somewhere that there are many publishers of this, and pandolfini's ultimate guide to chess was my first option but I think it's too soon. So are there any other books, what's your advice?
Sry I posted this in the wrong section of the forum.
