i am sorry i never got around to answering this. i have a list of incredible books from various authors i read a while back when i was really into NM that i could recommend. one day when im not feeling lazy and my fingers arent being awkward and i am focused enough, I might get around to typing that up.. until them, my favoritist, most highly recommended books/author:

I cannot recommend this guy highly enough. I have seen him at a 2 hour seminar and he is inspirational in his focus and dedication. It's better to start out with spell because he lays a lot of foundation there, but either book is a masterpiece.
