To write unpredictable scenes, try being unpredictable.
Plotting a novel can be a lot of fun, but it can also get a little tedious at times—trying to figure out the next step of a puzzle, crafting the perfect response to every choice your characters make, deciding when, where, and if you need a plot twist. When the muse is on your side the story flows quickly, but when she’s not?
For those days, try treating your scenes like a game of chance to kick start the muse and keep readers guessing.
