I count myself lucky to have worked with Rebecca on my debut, Black Water Rising, and consider her one of my writing family now.

Rebecca has such as a keen eye not just for those missing words or misplaced commas, but for those inevitable bits and pieces that cause contradictions in the editing process.
I can’t thank Rebecca enough for helping me bring de Silva and Barclay into the world, and I’m so thankful that she agreed to work with me on my first ever novel. I look forward to working with her again.

Author of BLACK WATER RISING, shortlisted for the McDermid Debut Award 2025

If there is something more you could want in an editor than what Rebecca provides, I must confess I’m at a loss to know what that is. She is a thorough professional with more than just a fantastic eye for detail. She knows story, inside and out, and she utilizes her story sense unerringly in the single-minded goal of making your prose the very best it can be. A joy to work with, she makes everything she touches immeasurably better. Her story notes are inspired, her copy edit exacting, and her formatting help is the cherry on top. Highest marks.

Thriller Author & Screenwriter

I turned to Rebecca when I was in crisis mode with my fourth book and she totally sorted my head out! Her comments were thoughtful, nuanced and incredibly helpful, and really helped push my manuscript further. She was at all times engaged and encouraging, and took the time to go over everything with me for clarity, coming up with some brilliant suggestions. I engaged her twice for this book and wouldn’t hesitate to do so again or to recommend to a friend. She’s made me enjoy a structural edit – words I never thought I’d say!!

Lizzy Barber
Richard & Judy Bestselling Author of Psychological Suspense including My Name is Anna, and Out of My Depth

I worked with Rebecca on the novel Angel Maker, and was drawn to her due to her experience with the genre, as well as her immediate enthusiasm for the project! It’s always great to work with someone that you feel, as a writer, is passionate about both their work, and the book they’re working on. With Rebecca, things felt easy…

Rebecca’s experience in crime and thriller really helped me to shape and polish the novel into something that my readers seem to really respond to. She was able to tailor her services to me to meet my perhaps unconventional needs, and the project was all the better for it.

Her perspective, professionalism, and skill as an editor really brought the novel up to a new level, and I hope that we can work together in the future on more novels to come!

Any writer would be lucky to have Rebecca as an editor. I cannot recommend her highly enough.

Morgan Greene
Crime Fiction Author

I feel so lucky to have Rebecca. Her line and copy edit on my novel was detailed, comprehensive and exceeded my expectations. She responded quickly to any queries and I have no doubt that her suggestions have significantly improved my manuscript and prepared it for publication. I’m only sorry I didn’t get Rebecca to do the developmental edit as well. I can highly recommend Rebecca Millar Editorial and will definitely use her for my next novel.

Annette Leigh
Crime Author

I’ve worked with a lot of editors over the years, and Rebecca is up there with the very best. In fact, I’m not sure I’ve ever had such detailed, insightful notes that just made everything so much better. Her feedback left me inspired, energized and confident in what I needed to do next and all the 5 star reviews (and great sales) are down to her. Thank you.

Michael Dylan
Crime Author

Rebecca was recommended to me by a fellow author, and I haven’t been disappointed. Her edits are detailed and insightful and have made my books so much better than they were originally. Rebecca is conscientious, and all deadlines are met. Rebecca is always there to discuss and brainstorm any issues which come up and her communication skills are excellent. I would wholeheartedly recommend her.

Sally Rigby
Author of the Cavendish and Walker, and Pi Sebastian Clifford Series

Rebecca Millar Editorial was incredibly helpful in developing my latest novel, pointing out gaping holes in my plot logic which would have never occurred to me. More importantly, she made me a better writer, gently improving my style with her edits. I would have no hesitation in recommending Rebecca – she’s fab.

Tim Adler
Psychological Thriller Author of Over My Dead Body

As a professional writer in Hollywood with thirty years of major motion pictures and network television series under my belt, I have worked with countless creative editors of my work of every level of experience and capability. Rebecca ranks in the top 1% of all of them.

Rebecca takes an immediate personal attachment to the project while zeroing in on the author’s vision. While it is clear from every edit and note that she wants what YOU want for your work, Rebecca is bold in pointing out where your work strays from your overall intentions.

Her grasp on style and practices, structure and punctuation are excellent. Her knowledge of what publishers expect and the desires of the public are pitch perfect.

Rebecca is extraordinarily meticulous and thorough. This begins on page one and continues to the final period. Her stamina never flags and her dedication to her work and making your project the best it can be is a joy to experience.

Rebecca is friendly, communicative, and utterly dependable. Her fees are reasonable, the equal of her work, and are worth every penny spent.

I am looking forward to working with Rebecca again. Once you’ve found Ms. Millar you will never need or want another editor.

Michael Frost Beckner
Espionage Thriller Author & Screenwriter of 'Spy Game', Starring Brad Pitt and Robert Redford

Rebecca’s work on my novel was fantastic. She challenged me to push and improve my book’s narrative and characters, as well as my writing in general. She is encouraging and supportive, and her notes and ideas were insightful, clear and well-judged. I can’t recommend her highly enough and hope to work with her in the future.

Simon McCleave
Bestselling Crime Author of Di Ruth Hunter Series

The editorial service provided by Rebecca was exceptional. I knew my manuscript needed some work but was struggling to take my writing to the next level. Rebecca’s insights were absolutely spot on and have pushed my story and craft on by several levels. I can’t recommend her highly enough.

A J Wills
Psychological Thriller Author

I cannot leave high enough praise for Rebecca. I began working with her in November 2020 for a developmental report and edit. When I received the finished product, I was shocked at the amount of work she had done. Her insights into my manuscript were in-depth and invaluable. She is a true professional who delivers a thorough, quality product in a timely manner. My work is so much better for her input. Initially, I was concerned that our small differences in culture (I am in the U.S., she is in the U.K.), might prove to be a challenge when editing my work. She assured me that she had edited manuscripts from authors all over the world. My concerns were really no concern at all. She was right, and in fact, her viewpoints provided clarity into issues of culture that I had not realized I was being insensitive. Rebecca is a gem.

Kelli Rueth
Thriller Author

It was wonderful working with Rebecca. I highly recommend her services. I used her for a developmental and copy edit. She helped me figure out the right services based on my needs as a new author. I’m extremely pleased with her communication and her professionalism. She is excellent at what she does. She saw things I didn’t see and pushed me to work my manuscript harder. I learned a lot from Rebecca and would use her again with my next novel.

Jamie L Fry
Psychological Thriller Author

I’ve never written a novel before … so all I can say is Rebecca is absolutely fantastic. How she grasps and remembers details in your story to ensure consistency is execptional. But that’s not the impressive part. It’s the way she gets you to push your writing style, that every action has a cause and effect, making sure a thread of a theme flows through your story and her input to a plot – I would not hesitate in recommending her. She is worth every penny. I’m only suprised she has not written a book herself!

Ian Bates
Crime Author

What can I say about Rebecca’s skills? Undoubtedly the best in the business. Rebecca’s close attention to detail, her command of the English language and understanding of the crime genre puts her head and shoulders above the rest. I worked with Rebecca on my book The Web They Wove, and I found her comments to be constructive and I know they will only make the book better for her input. Thank you, Rebecca, for being an absolute pleasure to work with and I hope this is the first collaboration of many.

Catherine Yaffe
Psychological Thriller Author

It was a real pleasure working with Rebecca. She was able to tailor her services to meet what I needed and what would fit within my budget. She was always clear and quick to communicate and professional in her approach. The final report showed the skills of a careful and discerning reader/editor and many of her thoughtful and well-articulated comments rang very true. She was prompt to answer my follow-on questions and I feel confident now that I know what direction I need to take to help develop my manuscript to the next level. Thank you Rebecca.

Lucy BH
Espionage Thriller Author

Rebecca’s edits and suggestions were spot-on – she caught the areas I already suspected were weak, and a whole lot more, especially inconsistencies in characters. She knows the business, understands what can be left unsaid, and what has to be overtly exposed. I recommend her without reservation, and hope she’s available for my next book!

Joshua Green
Espionage Thriller Author

Rebecca did a wonderful job on the edit of my novella, PLAYOUT. From the moment I read her sample edit I knew she understood both me as a writer and the nuances of my characters. One of the aspects I like the most about Rebecca’s work is that she provides fair and positive feedback that allows me to develop my own style rather than a ‘one style fits all’ situation.

I highly recommend her work, in fact, I’ve already booked Rebecca for my next book later this year.

Mark Mannock
Action/Thriller Author

I wasn’t convinced I needed Rebecca at first [but] not only did she help me craft the book proposal, her edits of the first three chapters of the manuscript were eye-opening. She uncovered a whole raft of opportunities to sharpen the manuscript and made a material improvement on the story. Her comments were thoughtful, sensitive, directional and, upon reflection, imperative to the story. Add to this her communication through the process and the fact she delivered the work ahead of an agreed deadline… I have absolutely no hesitation recommending Rebecca and look forward to working with her again in the future.

AJ Frazer
Thriller Author

Rebecca's feedback is inspiring to read and she makes the work a hundred times better with her great insights. The fact she is a joy to work with as well is just icing on the cake.

Crime Fiction Author

It was a real pleasure working with Rebecca on my novella. I have picked up so much through Rebecca’s developmental feedback, most of which can be applied to my future novels. Her comments were clear, thorough and most importantly, honest. Rebecca’s feedback has truly transformed and tightened my novella into something that I now enjoy reading! She was able to identify plot holes and make recommendations and suggestions that made the story read better overall. I have already recommended Rebecca to other authors and will definitely be reaching out to her again. Thank you!

Arti Manani
Psychological Thriller Author

Working with Rebecca has been an absolute pleasure. She stays in contact, exudes enthusiasm, and has provided an insightful and detailed assessment of my manuscript — with pages of suggestions that I continue to work through as I edit my work. I would highly recommend her services.

Jo Dixon
Psychological/Domestic Thriller Author

Rebecca is a brilliant editor – smart and intuitive with excellent attention to detail. She is reliable, a good communicator and a pleasure to collaborate with. I highly recommend working with her.

An excellent job

Vaseem Khan
Author of the baby Ganesh Agency Detective Series and the Malabar House Historical Crime Novels - and Chair of the Crime Writer's Association

I hit the jackpot when I first reached out to Rebecca and we decided to collaborate on a first book in a new series. So many things popped up during this year, and Rebecca was wonderful in accommodating me with schedule changes. But it was the input and suggestions on the manuscript that have been worth every penny paid. The report she prepared was comprehensive with specific examples within my MS, and suggestions, both broad and specific, which are invaluable. Not only did she improve my MS, but my writing overall. I highly recommend her for any author – new or experienced. She will absolutely make you a better author.

Leanne Kale Sparks
Author of the Kendall Beck Thriller Series

Rebecca is a wonderful editor and has been instrumental in my writing process as a novice novelist. She guided me sensitively and incrementally to better understand my characters and situations, as well as helping me to develop a more engaging writing style. I’ve benefitted greatly from her suggestions and insights, and her feedback was always encouraging, even when pointing out flaws in my story. I really felt in safe hands, and that gave me the confidence to push myself and my manuscript much further than I would otherwise have done. I cannot recommend Rebecca highly enough!

Helen Ernst
Mystery/Suspense Author

I brought Rebecca in for a developmental and copy/line edit when I’d hit a wall and just couldn’t get that extra “zing” I was looking for. With her sharp eye and expertise, she was part book coach, part weaver of magic. Forcing me to always go deeper, she made my story so much more nuanced and intriguing. I can’t recommend her highly enough.

Karen Dodd
Mystery/Suspense Author

Rebecca edited my first-in-series crime novel and did an exceptional job. Her comments made me dig deeper into my main character’s motivations and bring the noir elements of the story to the surface. Her approach ensured that the end product would satisfy readers of the genre. It was a great experience, and I’d be delighted to work with her on future projects

Bronna Nilsson

It was a pleasure working with Rebecca. Not only did she keep me informed on her progress with the manuscript, she did a great job of pushing me further with the story. I saw things in a way I hadn’t before and was able to add more subtext and nuance to the story which made it stronger.

Glede Kabongo
Domestic Suspense Author

Rebecca was a dream to work with. Friendly and professional, she was also communicative and flexible with my changing project needs. I highly value the services she offered and her editorial feedback went beyond what I expected. Will definitely work with her again.

Elena Kaufman
Thriller Author

My most important requirement when finding an editor, was to find someone who understands writers who lack confidence. Rebecca put me at ease every step of the way. I will always recommend her, and would happily work with her again.

Terri Lauri
Historical Crime Author

I’d hit a wall with my first manuscript. I knew it needed work but as a writer who hadn’t ever written a full manuscript before, I didn’t know what, or how, to make improvements. When I received Rebecca’s editorial assessment, I had the clarification I’d been seeking! Her report was comprehensive, clear and spot-on, highlighting the areas I’d suspected needed work and also things I hadn’t thought of. I would recommend Rebecca’s services to any writer and look forward to working with her again.

Alyssa MacKay
Psychological Thriller Author

It’s my first time publishing a book, and I couldn’t have picked a better editor. Rebecca has been very good at communicating things that need changing. She speaks professionally; very encouraging and supportive. She’s thorough, and she delivers ahead of time. I highly recommend Rebecca, and I hope to work with her again in the future.

Ace Campillo
Author

Rebecca’s work is incredibly respectful and constructive. I was terribly worried that any editing service would take away my voice from my books but Rebecca [did] excellent work improving the manuscript whilst protecting my writing style. Her comments are clear and empowering. I can’t wait to work with her again.

Alexandra Luz
Author

Rebecca was a pleasure to work with. She brought a level of enthusiasm and professionalism to the project that was greatly appreciated. She is an excellent communicator and has a keen eye for detail to ensure your project can be the best it can be. If you have the opportunity to collaborate with Rebecca, I strongly recommend doing so. She is talented, professional, and it is my hope to work with her again in the future!

Tyler Flynn
Thriller Author

Rebecca Millar is a rare fiction editor – her feedback is so detailed and comprehensive, it has thrown a spotlight across every level of my manuscript, opening up all the possibilities. In this, it is supremely constructive. I cannot recommend Rebecca enough.

Crime Fiction Author

Excellent from start to finish. Rebecca didn’t simply edit my manuscript, but remained a valuable participant when the time came to implement the changes noted. Always on hand. 100% would recommend.

Crime Author

Rebecca did an amazing edit on my first novel. She offered insightful, detailed and valuable feedback that took my story to the next level. The edit helped me develop my characters, plot, and structure. Rebecca opened my eyes to issues I did not pick up on myself. Her knowledge and expertise in crime, suspense, mystery, and thriller helped pinpoint what was missing and what the manuscript needed to fit my genre specifically. I highly recommend Rebecca and I’m excited to use her service in the future.

Psychological Thriller Author

Rebecca did an amazing job with my first novel and helped it sound and feel so much better. She provides good suggestions that add more depth to a scene through a few words or a sentence that I hadn’t even considered. Hoping to work with her again on the rest of the books in my series.

Jeff Smith
Crime Fiction Author

Excellent service […] Rebecca put my anxieties at ease from the very beginning. Can’t thank you enough, Rebecca.

Police Procedural Author

When I invited collaborations, I had several very good offers but Rebecca was the only one who asked me some questions first, about how long I had been working on the manuscript and what stage I felt I had reached. This is why I decided to go with her, as she seemed to be thinking more widely about the whole project and what type of edit would be best for me. Our communications were very straightforward, I was kept up to date the whole time and the final report was delivered a little ahead of schedule.  

There was plenty of detailed feedback, some of which I agreed with, some I didn’t, but then that is the point of getting a second opinion – it enables you to look at your work from someone else’s perspective, and to ask yourself questions about how it holds up. I would certainly recommend Rebecca to anyone else who is looking to take a step forward with their work.

Edward Kellett
Espionage Thriller Author

Working with Rebecca has been an amazing experience. She takes the time to really understand the manuscript and provides highly detailed and highly useful feedback.

Erik Meyers
Cozy Crime Author

Rebecca provided a very professional, clear and friendly service, with razor sharp insights to help develop my novel. In particular her input regarding structure and methods to develop the emotional connection between reader and protagonist have been invaluable, not only for this manuscript, but for future work. I would highly recommend.

Brid Cummings
Suspense Author

Great job! Exceeded expectations! Gave me actionable advice not only for this manuscript but also as a template when I am working on future rough drafts. She clearly spelled everything out during our entire engagement.

JD Murphy
Crime Author

Rebecca provided an excellent copy edit. Her feedback was very insightful, allowing me to strengthen my novel. She maintained great communication, answered all questions that I had, and she even delivered ahead of schedule. I would definitely recommend her to others.

Thriller Author

Ms. Millar is not only consummately professional, her friendly consideration and approach offers excellent guidance and encouragement. As my writing/publishing needs grow, she will be first on my list for consultation.

RD Hathaway
Adventure Thriller Author

I was so happy with the insights and corrections Rebecca provided as a line edit for the first three chapters of my novel, that I am [planning to hire] her to complete an editorial assessment for the full novel. Her comments were clear and on-point!

Scott Burdick
Author & Screenwriter

This was my first experience [with] having an editor look at my work. I couldn’t have chosen a better introduction than working with Rebecca. Her active communication, engagement and enthusiasm for my project were exemplary. Above all the quality of her work was excellent, giving me plenty of insightful, challenging and most importantly actionable feedback that is helping me take my manuscript to where it needs to be. I heartily recommend Rebecca and will be looking to work with her again in the future.

JC Mcrae

I enjoyed working with Rebecca, very much. She is very detailed. She gave me a lot to think about and allowed me to see things that I had missed. If you want to make your novel the best it can be, then I would strongly recommend her. I would not hesitate to have her edit another book of mine.
