It is by no means exhaustive and I've yet to pick up any how-to writing book and not learn something but these I found exceptionally helpful. I believe if you read and apply these books you can't help but to become a good writer, assuming you have the natural gift of story-telling and a basic command of the English language.
1. Self-Editing for Fiction Writers, Browne & King.
My first writers conference someone suggested this book. It's funny to think that I almost didn't put out the $10.00 on it. It turned out to be the best money I've ever spent on my writing career. No writer should be without this book. If there's a bible of fiction writing, this would be it. I would gladly have paid nearly any amount of money to gain the knowledge I have from this one.
2. Word Painting
Setting a scene is absolutely imperative in bringing a good story to life. Yet so few new writers do this. We have instead, talking heads who play out the story in a room I picture as all white, with no background noises, no grounding of the setting in any way. This book will help paint the scene which every book, no matter its genre desperately needs. And while I know this is going to look like shameless self-promotion, I think reading my debut, Crossing Oceans (Gina Holmes) will do just as much to teach scene setting as any how to book. If painting a scene is your challenge, these two together might just finally make it click for you.
3. Techniques of the Selling Writer
This book isn't the easiest read. It's a little dry, but if you can absorb the lessons within it, it will take you from good to great in the area of laying out your story. For me, I was writing down the bones of a story, sailing through a scene so quickly that the reader felt like they were being told a story, rather than living it. What this book did for me was teach me small action, reaction units and how to write them.
For instance, instead of "She grabbed the steering wheel and sped off," "She wrapped her shaking hands around the cold leather of the steering wheel, threw her head back to be sure he wasn't still standing in her path. Part of her hoped he was. Running him over would be doing the world a service. Nothing but a dried brown meadow stood behind her... "
4. On Writing, John Gardner
This book taught me the absolutely necessary concept of not pulling the reader out of the continuous dream. He also doesn't sugar coat what it means to be a novelist, who's cut out to make it and who isn't and what he finds helpful to writers and what he finds to be a hindrance to them growing. It is a fascinating and quick read.
