Chaos Theory is a very good book. I read it all in one sitting and it was just a phenomenal work. I would also recommend For a New Liberty by Murray Rothbard.
I have begun to read MES (still in the intro parts), and have the Murphy's Study Guide. My question is, how does one best use the study guide? Should I read his guide on a chapter, then the chapter in MES, or read MES then read the part of the study guide?
