I always get leery of books below the color belt level. The risk you run into is lower ranking students who read a book and misinterpret what it says out of lack of experience. As a color belt and junior black belt (1-3 Dan), your first priority is your Instructor. Above black belt, books can complement actual instruction if approached properly. Problem is, many people don't know how to differentiate between useful and junk.
I've read Y.H Park's books. Okay but not great. I suppose if you're Jidokwan they're not bad.
Richard Chun's books are really good. Some of the few I recommend.
