Four-star review of The Emotion Thesaurus second edition by Angela Ackerman and Becca Puglisi
An improvement over the last version of the book I used a few years ago. Expanded to 130 entries so you can find most emotions you can think of, and for each a long list of physical signals and behaviors as well as shorter ones of internal sensation and mental responses. Acute and long-term responses are also addressed. This is a good reference book for when you want to show a characters emotional response to something that occurred.
