Book excerpt: This fiction-editing guide shows authors and editors how to recognize shown and told prose, and avoid unnecessary exposition. Louise Harnby, a fiction editor, writer and course developer, teaches you how to identify stylistic problems and craft solutions that weave showing and telling together, and understand why there's no place for 'don't tell' in strong writing. Topics include: Shown and told prose in different scenarios; the relevance of viewpoint; when exposition serves story and deepens character; and tools that help writers add texture.
