Of all the troubles a beginning writer often has, style and tone tend to be at the top of the list. Whether we call it Voice or Theme or what-have-you, fiction writing is all about that mysterious thing.
People often make the mistake of assuming that storytelling is about events. Events are easy. Events can follow a logical path from A to B to C to Conclusion. It’s not that plotting is simple. It’s just that it is the most mechanical aspect of storytelling, the most quantifiable, and thus, the easiest part to focus on. It’s easy to teach technical rules, and much of plotting is technical. It’s often the foundation where the story begins, but without Voice or Tone, a story is nothing more than that. Believe it or not, we don’t usually care about those stories.
