Rosie Walker – Editor

Copy editor, proofreader, and book coach who has worked with Hachette and HarperCollins. Specialises in psych thrillers and women's fiction.

Overview

I'm a copy editor, proofreader, and book coach specialising in psychological thrillers and women's fiction. I've worked with 50+ authors at various stages of their writing journey, and many of them are now published.

My Masters in Creative Writing taught me the ins and outs of structure, pace, plot, and conflict. And I've navigated the novel writing and publishing process from start to finish: I'm also an author with five trad-published novels of my own: Secrets of a Serial Killer (2020), The House Fire (2022), The Baby Monitor (2024), My Husband's Ex (2024), and The Bride's Secret (2025) published by HarperCollins and Bookouture.

If you're looking for an editorial partnership with someone who'll tell you what's really working in your writing, I'm the editor for you. I value positive feedback as much as clear guidance for what can improve. I know what it's like when you've done everything you can and you're ready for another set of eyes on your work. I also know how important it is to feel like your editor is on your team: we'll work together to shape your book into the best possible version of itself, and you'll feel supported throughout the process and beyond.

I provide a range of editorial services for writers at all stages, from plot-tightening big-picture developmental edits and editorial assessments, through detailed line and copy editing, right up to the final touch of a proofread and polish. I also provide book coaching, which is ideal if you're looking for someone to guide you through a tricky part of your process or to help with novel planning or queries.

Communication is key, and I'm always up for a chat: if you want to know more, please send me a message and we'll set up a call.

Rosie completed a copy edit on my 40,300 word manuscript. She completed the work ahead of schedule, provided a Style Sheet and exceeded my expectations. Her work was detailed and very thorough. I would definitely work with Rosie again!

Rosie was very helpful and caught many mistakes that others had missed. When I reached out to her for additional questions, she was quick to respond and thorough in her explanations. I would happily work with her again.
