Book Editing and Proofreading

I am seeking an experienced fiction Line Editor for a completed ~130,000-word hard sci-fi / speculative fiction novel set on a tidally locked planet. THE PROJECT & MANUSCRIPT: The story revolves around two isolated human settlements (one in permanent radiance, one in fixed darkness) surviving extreme environmental conditions, mechanical degradation, and complex reproductive ethics. The tone is atmospheric, quiet, grounded, and technically precise. THE DRAFTING PROCESS & EDITING NEEDS: To be completely transparent about the project's history: the story, world-building, character arcs, and plot are 100% my original human creation. AI helped with portions of drafting. Because AI models default to specific verbal habits, I need a dedicated human line editor to polish the prose, vary the rhythm, and ensure the final manuscript reflects a distinct, natural human voice. KEY FOCUS AREAS FOR THIS EDIT: 1. Sentence Variety & Cadence: Smooth out staccato, metronome-like sentence rhythms into varied, flowing prose. 2. Character Voice & Dialogue: Eliminate repetitive "echo-and-correct" dialogue tropes so characters sound like distinct individuals. 3. Technical Preservation: Retaining the dry, grounded mechanical texture and sci-fi worldbuilding details. 4. Copyright Security: Performing genuine, sentence-level rewrites with Track Changes ON to establish indisputable human prose authorship. DELIVERABLES: - Full MS Word document with Track Changes enabled showing all line edits and rephrasings. - Editorial notes/letter providing feedback on character voice and narrative flow. REQUIREMENTS: - 100% human editing process (no AI tools, ChatGPT, or automated rewriters used in your editing workflow). - Comfortable working in MS Word or Google Docs with Track Changes enabled. When applying, please share your rate, turnaround time for a 130k-word manuscript, and a brief note about your experience with fiction or hard sci-fi.
