Adana Gardner Marfield – Editor

Let's make your story sparkle! Kid Lit, YA, or Adult -- I will help sculpt your book or screenplay into the masterpiece you've envisioned.


I have witnessed, nay caused, the death of many a red felt pen! In addition to countless essays, I have copyedited six published books and many screenplays, including Paramount's 2022 film release, RUN & GUN. I am a keen-eyed proofreader who will (much to your annoyance) find every typo on your page.

I am proud to be a retired high school English teacher. I achieved National Board Certification and was honored to be named Los Angeles Teacher of the Year 2012.

I have written a children's book and a screenplay, and I am currently working on a memoir, so I very much understand this labor of love.

Collaborating with others is my greatest joy. As a copyeditor, you can expect me to spot inconsistencies and offer suggestions to improve the flow and pacing of your work. As a proofreader, I will edit your manuscript with flawless grammar, spelling, punctuation, and spacing. Let's get going on your project! I am here to help.

Reedsy was recommended to me by a friend, but I didn't really know what to expect. I have been collaborating with Adana Gardner Marfield on both copy editing and proofreading, and she has far exceeded my expectations. Adana is enthusiastic but honest; responsive but thorough; and friendly and supportive in a very professional way. Before I submitted my young adult novel to Adana, I thought that...

Adana is an amazing editor. Her notes were extremely detailed, and were exactly what I needed to take my screenplay to a professional level.
