Mary Jean Jones – Editor

I've been proofreading practically my whole life. Since 2019 I've focused on copy editing ebooks, specializing in historical fiction.

Overview

I. Love. Words. I have an excellent command of the English language as well as a background in Romance languages.

I have been proofreading before and throughout my corporate life but gravitated toward copyediting and line editing ebooks seven years ago when I noticed the need to clean up the writing in ebooks. I have worked on over 25 books, including one that received a Book Excellence Award in Historical Fiction. I am comfortable working with English, dialects, Romance languages, and even some German. Most importantly, my language background helps me understand an author's voice - your voice - and I will work with you to perfect your writing.

As usual, MJ did a great job on this 3rd book. She caught all my little errors, and a confusing piece of my story. Won’t hesitate to continue using her for all my books.

MJ was a pleasure to work with. She was thorough and identified several issues that I had overlooked. I will be using her again for my follow-on novels.

I was very satisfied with the working "partnership" I enjoyed with Mary Jean. In addition to the nuances (corrections) re., grammar and punctuation, she gave thoughtful opinions on certain rewrites I submitted, as well as encouragement every step of the way. In that respect our work together was ...
