Query: Helpful to all Levels

I've always enjoyed Orson Scott Card's fiction, so I was happy to pick up his book on Characters and Viewpoint in writing. I found it quite helpful, and I believe it can provide insight to writers of all levels. I've already used it as a jumping off point for several of my own articles.Charles GramlichAuthor of Cold in the Light
