About Marinda

Looking for a freelance book editor who understands the entire publishing lifecycle? That’s me.

I’m Marinda, a publishing professional with a strong foundation in editorial project management, copyediting, and production editorial workflows. I’ve worked on hundreds of titles across genres and formats—from picture books and manga to emotionally rich adult fiction.

With a master’s in publishing from NYU and a certificate in project management from the University of Washington, I specialize in helping publishing teams deliver quality books efficiently and collaboratively.

I bring a unique balance of insight, organization, and editorial expertise to every project. Contact me for your production editorial needs today!

✏️ Copyediting

As a freelance copyeditor with over a decade of experience, I provide detailed and voice-conscious book copyediting services for fiction, nonfiction, picture books, manga, and more. I focus on grammar, punctuation, consistency, and style while preserving the author’s intent. Whether you’re a publisher, independent author, or literary agency, I’ll help ensure your manuscript is polished and publication-ready.

👓 Cold Reading

My cold reading services offer a fresh, first-time-reader perspective on your fully laid-out pages. This step is especially useful for catching overlooked issues that can affect flow, tone, or clarity. I specialize in cold reading for illustrated books and manga, offering gentle polish and editorial quality checks during late-stage production.

🔍 Proofreading

I offer professional proofreading services for print and digital formats, including final pass reviews of galleys and designed pages. My goal is to eliminate typos, formatting errors, and style inconsistencies before your book goes to press. If you’re looking for a book proofreader who understands the nuances of layout and production, I can help ensure your title is clean, correct, and on-brand.

📝 Slugging

Need a clean, structured manuscript breakdown before layout begins? I provide accurate, efficient slugging for publishing projects. My slugging work supports smooth transitions between editorial, design, and production teams, especially for complex formats and licensed titles.
