A must-have for any writer: my characters are frowning much less, which makes for a happier reader. Honestly, a brilliant resource. Each emotion is split into sections: physical signs and behaviours, internal sensations, mental responses, acute or long-term responses, signs the emotion is being suppressed, and what each emotion may escalate or de-escalate to (which page numbers directing to those stronger/weaker emotions). I'm finding that it is quite nice to tell the emotion I want to bring across in the first draft, and then use this book to really flesh out and bring things to life in the drafts that follow. It also makes character-building that much easier, as I can pick a few key responses to each emotion and make my characters' reactions more unique to them..
