Professional manuscript editing services offer highly specific and valuable feedback. An editor will not simply tell you this is boring. They will tell you that it slows down on page 80, that there is too much description. Attempt to eliminate 150 words to maintain the flow of the story. They give you a clear-cut outline of your next draft.
Try This: When you have reader feedback but are unsure what to do with it, it is time to hire a book editor.
