Rosie Walker – Editor

Novelist and editor specialising in psychological thrillers and women's fiction, offering developmental edits, copy edits and proofreading.


I'm a writer and editor with two published novels of my own: Secrets of a Serial Killer (2020), and The House Fire (2022), both published by Harper Collins' One More Chapter. I'm currently writing my third novel and offering my services as a freelance developmental and copy editor, specialising in psychological thrillers and women's fiction.

I have a Masters in Creative Writing, which 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 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'm here to give other authors guidance and support to get your novel to the next stage through developmental edits: assessing your manuscript to help you tighten your plot, crank up the tension, and understand what your book needs to grip the reader on every page. When you've nailed your plot, I also offer copy editing services where I forensically examine your novel on a line-by-line basis to ensure every paragraph does the best work it can.


"I’m a published travel writer and I’ve relied on Rosie’s editing skills for the past five years. Her keen eye and attention to detail has ensured everything I send out is word-perfect, from newspaper articles to competition winning pieces. Recently I used her developmental editing service for my psychological thriller manuscript and she was amazing, showing me where the action needed to pick up on the page, helping me restructure the twist so it’s perfect and also letting me know when something was working well, which was incredibly helpful and motivating."
-- Suzy Pope, Travel Writer and Novelist

"Rosie is an excellent editor who provides insightful, straightforward feedback. She has a great understanding of what captivates a reader, and spots any issues with pacing or plotting a mile off. She's an expert on structure and is an invaluable source of guidance when it comes to tackling the big developmental work. In addition, she has a good ear for language and can help rework paragraphs and sentences until they flow. After working with her for over a decade, I would highly recommend her as an editor, whether you're looking for big picture developmental work or in-depth copy editing."

Rosie was fantastic to work with! She communicated clearly and delivered her work according to our agreed upon timeline. Her editing touch was light but thoughtful and precise and her work contributed to my writing being more consistent, polished and ready for the next stage of the publishing adventure. She posed some great questions in the margin which helped me see the novel through the reade...

A published author herself, she knows her trade as a writer, not only a teacher and coach.
