Ever since I attended Margie Lawson's ACFW workshop on Empowering Character Emotions, I've hungered for more information on character's visceral responses. I intend enrolling in Ms. Lawson's month-long course in character's emotions. Until then I'll read books on the subject.
Creating Character Emotions by Ann Hood is the first book I read. After a short introduction and chapter on tightening fiction, the reference begins. Thirty-eight different emotions are outlined.
Each chapter of emotion offers a lesson on the sentiment, giving "good" and "bad" examples of prose. The chapters end with exercises to stretch the readers writing skills.
This is a decent reference tool to have among your how-to books. However, if you want a more in-depth study on how to write character's emotional responses, sign-up for one of Margie Lawson's online classes.
