First—Congratulations! You're either writing or have written a novel and you're preparing for a deep dive into the content. The Four Types of Editing provides a good idea of what to expect when editing the different layers of your manuscript.
For the purpose of knowing what to expect from me, the content edit provides feedback regarding your manuscript including the flow, consistency, plot strength, fact checks, character arcs, and dialogue. Line edits review how your words are crafted. The flow of your sentences and paragraphs. Line also concentrates on voice, readability, and style.
Summarizing, content and line involves reviewing progression, dissecting story and characters, and pulling sentences apart and then putting them back together again. That alone takes time. Consequently, time is required with your manuscript. Depending on the manuscript length and other factors, the process will take from two to four weeks to complete the content and line edits.
