Marie Valentine, Copy Editor and Proofreader

marie-valentineEditor of Fiction, Short Stories, Memoir, Poetry, Creative Nonfiction, Esoteric, & Experimental Literature

Offering Copyediting, Manuscript Evaluation, Proofreading, Formatting, Style Editing, Developmental Editing & More

Marie holds a master’s degree in communications. She has served as a book editor, news editor, business technology writer, poet, and micropress publisher of experimental works by contemporary writers.

I am so lucky to do what I love. The best part is the variety of amazing manuscripts I get to read. I enjoy both nonfiction and fiction, and I’ve had the pleasure of editing works by many talented writers.

As an editor I’m vigorous yet hands-off: I will find errors and inconsistencies with an eagle eye, but I like to let the work stand for itself. I won’t change anyone’s work into my own. I strive to find each author’s unique qualities and make those resonate.

If we work together, besides receiving the valuable critique of a professional editor, a writer will get advice on presentation. This can be as simple as discussions of formatting or as nuanced as query letters, agent submissions, marketing, and self-publishing. I offer free query package evaluations for my clients because I have acquisitions experience and know what publishers expect.

I am a fan of all my authors and have much respect for the work they do.

“This woman is outstanding!” – the Honorable Clifford B. Stearns, former U.S. Congressman and author of Life in the Marble Palace

“Marie was so great to work with. This was my first time working with an editor. She was extremely professional, yet had a very down-to-earth way of communicating her editing opinions. I feel like my voice remained fully intact. She just brought everything to a different level. I will definitely reach out to Marie for my future editing needs.” -John Ethier, author of the fiction novel, The Little Red Boat

“Was able to choose from a wide range of editors and Marie Valentine always executed her work with an uncanny sympathy and acuity, never once distorting my intention or tone.” – Lyn V., screenwriter

“Marie was an absolute pleasure to work with. It was my first time having a story professionally edited and I am so glad I chose Marie. Not only was she done far ahead of what she expected her deadline to be, she was extremely supportive and constructive. She tells you from the get-go what she considers your strengths to be and what she’ll be able to help you improve on. All her feedback was extremely helpful and inspirational and will not doubt improve my overall project. She never alters your voice coming through the writing and rarely asks you to remove anything from your project. Thank you again for everything. Your suggestions and expertise with editing are greatly appreciated and have helped this story reach its full potential. I cannot begin to express my gratitude for what you’ve done! It’s been an absolute pleasure to work with you. Your kind words and constructive criticism has been a huge confidence booster and inspiration for me to continue this path. I look forward to working with you again in the future!” – Gabe Mesquita, author of Champion

“Working with Marie has been wonderful. She provides consistent work with a positive attitude. She points out strengths and weaknesses and evaluates what can be done to turn those weaknesses into strengths. She was easy to reach, returned e-mails within 24 hours, and met each deadline (twice was early). I look forward to working with her again in the future!” – Jessica Gould, author of Shallow Foundations

“I really enjoyed working with Marie. She was professional and clear and kept her deadlines. Her edits and comments were on point and did not alter my voice. I look forward to working with her on future projects.” – S. Stephens, author of Between Right and Wrong

“This is exactly what I wanted. I have worked with editors before, and the changes they made usually didn’t work very well for me, but yours are just perfect. It is a gift to improve a text according to the author’s personal style and rhythm. I am happy I picked you.” – Miron Neghabian, author of Coming Home: The Illuminating Novel

“Marie Valentine has an eye for detail and a flair for originality in highly technical writing. It’s no mistake that she was the final oversight for many submissions of news, features, commentary and informational pieces in her years at Information Management magazine and website. Marie is a consistently curious reader and a stylistically solid editor, and she is an excellent, timely communicator of those unique skills. As she introduced me to the niche writing world of business intelligence, Marie passed on to me and others important daily writing insight and content resources, with both patience and grace. There is no editing or writing opportunity in which I would doubt Marie’s capabilities.” – Justin Kern, writer and former colleague at Information Management

“Your edits were superb! I liked that you were able to make corrections which enhanced the feel of the chapter without compromising the original voice of the story. You’ve been awesome!!!  I definitely feel like I made the right decision working with you. ” – Demethius Jackson, author of The Realmsic Conquest Series

“Marie displays both an administrative flexibility and the ability to meet unforeseen challenges, as well as a real capacity for making the editorial interventions that discriminates between true quality and mere excess. The vast array of projects she has taken on over the years stands as evidence of her willingness to experiment with new possibilities. The projects that Marie has tackled are successful and fully-realized – hers are not fragmentary pipe dreams but rather complete visions. That these efforts of hers often involve working collectively, adjusting to various personalities, and coordinating disparate groups of writers and artists, is an even greater testament to the depth of her ability. This unique combination of vision, dedication, and focus is what I have valued in my work with her, and it is precisely what I believe makes Marie an adept communications professional.” – Andrew Knighton, professor of English, California State University Los Angeles (former colleague at Visual Art Critics Union of Minnesota)

“I have worked with Marie as a freelancer, and I’ve seen her jump to challenges, adapt to change, carry out difficult goals, and help our publication distinguish itself. I was particularly impressed when I had an idea for a different way to tackle an old concept. I bounced the idea off Marie, and she made it work. She accepts feedback extremely well, and in a way that encourages a dialogue. You won’t go wrong with her.” – Diane Bacha, Publisher at Kalmbach Publishing Co. (former General Manager of MKE, A Journal Communications publication)

“I have known Marie for years, and we have worked together on multiple projects. Her hard work and creative spirit have always been an inspiration to me. Her love for language/writing/editing are clear, and she turns that into enthusiastic and insightful contributions to a project.” – Dana Sitar, author of A Writer’s Bucket List

“Marie is an enthusiastic, dependable and conscientious employee who would be a great addition to any project.” – Jean Schauer, former Editor in Chief at the BeyeNETWORK

She is very energetic, earning her masters degree while working full time, and a loyal, dependable member of the team.” – Mary Jo Nott, Editorial Director at Bloor Group

“I love having Marie as an editor. She truly engages with the work. She finds the inner heart of the piece and works her way out from there. I appreciate that she fields my questions regarding edits openly and promptly. She is more than I could hope for. If it were ethical, I would have her edit this recommendation.” – Mike Bahl, author of Scenic Utah

“Marie Valentine has edited three books I have written and we have co-edited several short-run chapbooks. Her keen intellect, critical eye for good writing and ability to process large amounts of complicated text in a short period of make her a valuable asset. Marie is impressively well-read and has been tremendous to collaborate with due to the broad range of literature which encompasses the breadth of her interest. I would highly recommend her in the areas of editing, proofreading, writing, analytical critique and inspirational encouragement.” – Wes Tank, writer, musician, and filmmaker

“Marie did an excellent job proofreading my manuscript. I enjoyed her insight and found her recommendations very helpful. I was impressed by her professionalism and the quick turnaround.” – Tessa Saks, author of What is Love?
