Writing the Other
Many writers avoid creating characters of different ethnic backgrounds than their own out of fear that they might get it wrong. To address this fear, Nisi Shawl and Cynthia Ward collaborated to develop a workshop that addresses these problems with the aim of both increasing writers skill and sensitivity in portraying difference in their fiction as well as allaying their anxieties about getting it wrong. Writing the Other: A Practical Approach is the manual that grew out of their workshop. It discusses basic aspects of characterization and offers elementary techniques, practical exercises, and examples for helping writers create richer and more accurate characters with differences.
