What Every Body Is Saying is an ex-FBI agent's guide to reading non-verbal cues, which will help you spot others' true intentions and feelings, even when their mouths are saying something different.

Coming to the US from Cuba at age eight and speaking no English, one would expect Joe Navarro to have a hard time socially.

But by the time he learned the language, the young boy had already made friends through his uncanny understanding of non-verbal cues and body language.

As an adult, Navarro spent 25 years at the FBI as an agent specializing in counterintelligence and behavioral assessment.

Now retired, Navarro regularly speaks as a consultant on body language, having appeared on multiple major news networks.

In this bestselling book, co-authored with psychologist and management professor Marvin Karlins, the former FBI agent explains how you can raise your nonverbal intelligence.
