Have an open mind. This means that if an editor tells you that your story would benefit from a different point of view, or that the three paragraphs you wrote to describe the meal your protagonist had for breakfast should be deleted, consider that you might be too close to the work to see it at its potential best. The choice is always yours to choose or reject an edit, but if you’ve hired a good editor, she knows what works and what doesn’t.
Did you know that the comma is one of the most controversial punctuation marks? This means that even the geekiest grammar Nazis at the Chicago Manual of Style will occasionally disagree on this cute little curlicue. What this means for the author is that you might wonder why we inserted a comma in one place but not another. Most book editors use the rules set forth in the Chicago Manual of Style. We use this in conjunction with Merriam-Webster. For issues covered in neither, we make our own editorial decision. There’s a reason the comma warrants an enormous number of pages in style guides. So, trust that your editor knows what he’s doing. Although hard and fast rules certainly apply to most areas of grammar, gray areas still abound. Chicago often defers to what they call “editorial judgment.”
