If you are fairly confident that your manuscript, story or article is in good shape without needing major structural revisions, then you may want to think about a line edit. A line edit differs from copyediting in that it addresses the creative content, writing style, and language use at the sentence and paragraph level.
A line edit focuses on the way you use language to communicate your story to the reader. Is your language clear, fluid, and pleasurable to read? Make no mistake, line editing a book is a time-consuming and painstaking process, but not only will it improve your current manuscript, but a line edit will give you the creative tools to become a better writer in ways you can carry with you to future projects.
