With nearly twenty years of book editing experience, Marie Valentine can significantly improve a manuscript, whether for submission to publishers or in preparation for self-publishing.

As an editor, Marie is vigorous yet hands-off: she will find errors and inconsistencies with a sharp eye but lets the work stand for itself. She won’t change anyone’s work into her own. She finds each author’s unique qualities and makes those resonate.

Marie knows how to spot inconsistencies in structure as well as style and spelling of key terms. She has passed the rigorous proofreading test of this editorial network, so you can trust her edits will clear up the typographical errors in your book.

Besides offering an objective critique from a professional editor, Marie provides advice on presentation. This can involve discussions on formatting the manuscript as well as crafting query letters for agent and publisher submissions, book marketing, and self-publishing.

Marie offers query package evaluations for all her clients who are interested in publishing traditionally. She has editorial acquisitions experience and knows what publishers expect.

“Marie, I can neither tell you how thankful I am to you nor express how delighted I was to see your email. I kept editing the manuscript as per your suggestions every day. This morning I finally completed it, and I am extremely thankful to you for going through it so patiently, sending it back so quickly and providing so many inputs and encouragement. Thank you, from the bottom of my heart. Every time I’d read this email or a comment about the tone and what you liked and what could be better, this book became more of a reality.

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.

“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

“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)

If it were ethical, I would have her edit this recommendation.” – Mike Bahl, author of Scenic Utah

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.

“I appreciated Marie’s timely responses and reasonable service prices. She was able to point out several areas where idea development was needed, as well as provide a basic skeleton for copy editing.” – (Author info on file with network)

I was extremely satisfied with the quality of the services I received. Marie not only took great interest in my book but provided me with appropriate corrections and useful suggestions as well. I used most of the suggestions she offered me to tighten up the text of my book. I was extremely satisfied with the cost of the service in terms of value. Not only was Marie submitting work to me before my deadline, but she did so in a manner which showed she had put time and effort into my book. Internalize, my book of poetry, is a piece of my soul, and Marie seemed to understand that wholeheartedly. To me, that’s priceless. Marie was prompt and timely when it came time to answer any of my questions. I was admittedly concerned about how interactions between an editor through email would pan out, especially since this is my first book. Marie made all those initial concerns disappear and that alone was worth the price. When I came across Marie, I had a good feeling about her. I saw she had experience with poetry, which automatically made me interested in hiring her. However, there was also a feeling that she was a very down-to-Earth person and was fully capable of helping me tight up my manuscript. I’m glad that gut feeling of mine was correct in that assumption!” – Joshua Handville, poet

“I can’t tell you how much I appreciate your feedback, the edits and your future offer of help. I really enjoyed your feedback. Thank you for the work, it was very professional and has made the words flow like butter.” – Danette Mondou, biography author
