Copy editing happens between the content editing and the proofreading stage. Unlike content editing, which looks at the entire book, copy editing breaks it into little pieces, examining it paragraph-by-paragraph, sentence-by-sentence.
At this level, the editor is checking for sentence flow, grammar errors, active vs. passive voice, and inconsistencies. While content editing might reveal major revisions that need to be done, copy editing usually reveals smaller problems, although those problems are no less important when it comes to reader satisfaction than the ones caught by a content editor.
Again, the relationship between editor and writer is very important, and to make sure that our relationship would be a solid one, I would read the first 2,000 words for free and return them to you edited so that you get a look at my style while I get a look at yours.
At this stage, I will also determine whether or not your manuscript is ready to be copy edited, or if it still needs content editing. Pricing
