This book has been called "the best book on poker tells" by many poker players since its release in 2012. It catalogs the most commonly seen poker tells displayed by both amateur and experienced players, and gives in-depth reasons why those tells appear the way they do. 

Most importantly, Reading Poker Tells gives a unique system for thinking about and remembering poker tells, breaking poker behavior into situational categories. This treatment of poker tells helps explain why some poker tells mean one thing in one situation but can mean something entirely different in another situation.
