It’s one of the trickiest tools on the writer’s workbench. Ignore it, and the most well-plotted scene ends up flat and forgetable. Use it with too heavy a hand, and a scene meant to be moving can tip over into melodrama. Wield it well, and it can elevate a book from merely “good” to “memorable”—the kind of book whose characters and story linger in a reader’s mind and heart long after they have turned the final page. Whether you’re just starting to plan your story, or are revising one—fiction or non-fiction—we’ll cover the use of this tool from a variety of angles, showing you ways to employ it at every stage of the writing process, from choosing your overall subject to choosing a small, single word.
