Verified identity


I'm a writer and editor with two years of experience as an author of two published novels: 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. While working together on my first novel, she was able to spot places where the plot lacked sufficient obstacles for the protagonist to face, and helped to brainstorm ideas for conflicts that would be compelling for the reader while staying true to my vision for the work. 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. Rosie has also been a great source of encouragement, with her feedback highlighting the elements that work just as much as areas that could be improved. 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."

If you are able to work with Rosie Walker, you are very lucky, indeed. She is spectacular. I've just completed my second developmental edit and first copy edit with her. With her guidance, my novel is going from strength to strength. She's a genius at emphasizing what you are doing well and then helping you achieve a high quality of writing throughout your manuscript. Not all editors can do tha...

Rosie Walker is joy to work with. She provides invaluable feedback in a constructive and motivating way. Her skills allow her to go directly to the issues, however, she also provides helpful solutions and alternatives. I really felt Rosie understood what I was trying to achieve and helped to improve my work considerably. Thank you so much Rosie!

I don’t know how I got so lucky! As a first time author with a completed novel, I didn’t know what I didn’t know. When I requested an editor who would work in a completely unrealistic timeframe, Rosie Walker was the only editor who explained a realistic schedule and warmed me off those who said they could produce a well-thought out developmental edit in the short time I requested. Add to that ...
