Sarah Mitchell
Manuscript Specialist: Copyediting, Proofreading & Style Consistency
Sarah is the final set of expert eyes every manuscript needs: precise, thorough, and fluent in every major style guide. She ensures your book is error-free, internally consistent, and ready for the press.
The Detail That Makes the Difference
I'm Sarah, and I've spent a decade doing the work that separates a good manuscript from a professional one. Copyediting and proofreading aren't glamorous, but they are the difference between a book that readers trust and one that quietly undermines itself on every page.
I work at two levels. First, the macro: internal consistency, voice coherence, continuity of character names, timelines, and facts. Then the micro: every comma, every hyphen, every sentence that stumbles even slightly. By the time a manuscript leaves my desk it is clean. Genuinely clean, not just spell-checked.
I'm fully fluent in Chicago Manual of Style, APA, MLA, and several house style guides developed by publishers I've worked with directly. I adapt completely to the conventions each project requires, and I flag inconsistencies rather than silently correcting them, because authors deserve to understand every change.
Whether your manuscript is a literary novel, a business book, an academic text, or a screenplay, I bring the same standard of precision. Nothing goes past me twice.

What Authors Say
“My academic manuscript had to meet the standards of a major university press. Sarah went through every citation, every heading, every footnote. The press editor told me it was one of the cleanest submissions they'd received. That was entirely down to Sarah.”

Caroline Bates
Verified Author
“I thought I'd caught everything before I sent my thriller to Sarah. She found seventeen continuity errors I had completely missed: characters appearing in two places at once, a plot detail that contradicted itself 80 pages later. Absolutely indispensable.”

Tom Ashford
Verified Author
“English is my second language and I was anxious about the editing process. Sarah preserved my voice completely. She corrected what was wrong without ever making the prose feel like someone else wrote it. That balance is rare and I'm very grateful.”
