Subtlety can mean the difference between a novel that works and one that falls flat.
The smallest change have a big impact on your writing. One word change, one shift in perspective, and everything’s different. Hopefully such changes result in a better story, but when they don’t, spotting what’s wrong can be frustrating.
Maybe you’re struggling with a story right now, or submitting one that’s getting good feedback, but just not quite landing anywhere, or having beta readers tell you it’s good, but not great, and it’s lacking something they can’t put their finger on. You know you can fix it if you could just find it.
Take a closer look and see if there’s a subtle reason that’s holding your novel back.
