Telling you how to go about writing fiction that sells isn't possible, really.
Please, in your next article, give some examples of why certain books sell in the different markets other than by author name recognition.
- Characters: Readers like to relate to the main character. They want to care about the character and to root for him. They want characters they can empathize with or, at least, characters they can sympathize with. They want characters that feel real and three-dimensional. Clichéd characters? Not so much.
- Plot: Readers want conflict. Why do the TV news shows run sensational story after sensational story? Because conflict interests us more than peace. When there's conflict, we need to keep reading to see how things will all turn out. Along with conflict, readers enjoy twisty surprises.
- Voice: Many readers don't notice a gorgeous voice when they read, but they will feel bored by a snoozer voice. And, yes, it's possible to have colorful characters and a thrilling plot and then to kill the whole deal with a voice that plods from paragraph to paragraph, stringing together one gray sentence after another. Pacing, word choice, rhythm, sentence variation—all of these are part of voice.
- Theme: Readers want to be moved, and the way you move them is by putting universal themes into your books. To move a reader emotionally, you need to plug into his dreams, his fears, his sorrows, or his joys. Nonfiction authors often hear that they should speak to a felt need, but what many novelists don't get is that fiction readers have mice that need to be trapped and wounds that need to be bandaged as well. Maybe fiction readers haven't identified their needs on a conscious level, but you, the author, will do well to analyze their needs before you write the book. Women who read romance want to be loved and cared for and protected, I think. What do lovers of fantasy want, do you suppose? Probably all readers want to feel safe and cared for. Those are basic human needs. So tap into those needs when you write your fiction.
