Its not a book for beginners, but it is a very good book to study.
My System by Aron Nimzowitsch

I felt that the section of the book on the centre indirectly gave me a better understanding of the opening principles and why some moves work better than others. it helped bring my rating on this website from 900 to 1200. It wasnt the only thing that helped but it was a good help. I learned to make my own moves rather than completely rely on theory made by others.
Okay thanks alot!
