The Body Language by Julius Fast was recommended by a very good speaker during a seminar I attended. I bought the book on Ebay. I found the book to be interesting and informative but somewhat difficult to read - somewhat like a college text - good information but didn't really flow easily so it took a bit of time to finish. If you watch and like that new television series "Lie To Me" you will find the book more informative. It deals with the body language on a more global scale - more in the understanding of the psychological dynamic rather than isolating individual mannerisms. Althought the author does go into detail about specific nuances of body language in group situations. In my opinion - it is worth the read - but not terribly exciting.
