It depends on how long your novel is, what kind of editing you're getting, and how dense your text is. As a ballpark estimate, you can typically expect a 4-8 weeks turnaround for an adult novel from 75,000-100,000 words long. It can be more for dense and longer novels or shorter for proofreading, children's books, or lighter books, depending on my schedule. I always give a time estimate and a turnaround schedule with my sample edits, so please inquire for an exact timeline.
