It is said that novels are not written, they're rewritten. A first draft of a novel is the author telling themselves the story. Progressing from that to a published piece of work involves editing and rewriting.

At writer.support, we have experience of working with authors on the three stages of editing: structural / developmental edits (crafting the overall shape of the story); on copy editing (focussing on the work's readability, and ensuring that your writing flows smoothly and makes sense to the reader); and proofreading (which highlights and fixes punctuation and grammar).
