Hi Laura,
You mentioned that you were really interested in Tae kwon do before, but classes were a bit expensive. Learning Tae kwon do or any martial art from a book is inferior to taking classes with an accredited black belt with experience.
It can't hurt to look over it as a reference and to get an idea of what its about

. I found a site that gives short reviews about many different Tae Kwon Do books. Enjoy.

Also if you happen to pass by the book store, I would recommend looking up any Tae kwon do book written by Grand Master Jhoon Rhee or Grand Master He Il Cho.
Best of Luck!
