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.

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.

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 novels of my own, 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.

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.

A note on AI: I do not use AI in my editorial work, and although I am comfortable working with authors who have used assistive AI to plan or polish their manuscripts, I don't wish to edit manuscripts written by AI.

Rosie brings a genuine interest and care to the work and a delicate touch when copy-editing that is really tough to accomplish. She was on time, communicative and answered questions even after the edits were complete. She caught so many things that I didn't otherwise see! Grateful!
