How to Read a Person Like a Book – Gerard I. Nierenberg & Henry H. Calero

This classic manual on nonverbal communication teaches readers how to interpret body language to understand the true intentions of others. By breaking down specific gestures—such as hand-to-face movements, posture shifts, and eye contact—the authors provide a toolkit for "seeing" what people are thinking during negotiations, interviews, and social interactions. It remains a staple for anyone looking to master the art of silent communication.
