Full manuscript edit

This is what I like to call “developmental plus.” I’ll provide an overview on what’s working in your manuscript and what isn’t, suggestions for possible reorganization to help fix what might not be working, an editor letter, and inline comments. Line edit habits you lean heavily on will also be noted, along with suggestions on how to smooth your personal prose, but will not be corrected throughout. For an additional  $30, I’ll also run two passes of your query letter, once before reading, for confusion’s sake, and once after, for suggestions on how to make it more specific and intriguing.

— priced at .008 cents/word.

Line edit overview

Your writing only gets better with practice, and a line editor can fix everything for you, or you can learn to fix it yourself. Send me 50 pages of your work and receive back complete line edits, along with a summary in letter form of what you rely most heavily on and need to be aware of going forward, to help the rest of your manuscript and future works shine.

Mentorship program

New and confused? Or experienced and lacking a writer family? Maybe you simply want someone to be able to read for you on your time, instead of on theirs… With this program, I will read through three revisions of your manuscript and be available for weekly check-ins to help motivate or brainstorm with you. I suggest you give me your best work, what you think is ready for an agent or at least a third draft. I’ll provide you with developmental thoughts and an editor’s letter, along with inline comments. After you’ve had time to revise, I’ll go through your story again to catch any places the smoothing wasn’t complete, along with doing a pass for line edits. You polish a third time, and I’ll proofread and do some copy editing – though I’m a very clean writer and reader, know that I’m not a certified copy editor, so this is just to get you started and as polished as I can help you be.

— priced at .025 cents/word.

“Mercer is a skilled writer with a keen editorial eye. She reads deeply, and her feedback is both astute and kind. I’ve relied on her insights for several of my manuscripts, and she’s always helped me to enhance what was working, pinpoint missteps, and identify areas that were ripe for improvement.”

Karla Manternach, author of Meena Meets her Match, and Never Fear, Meena’s Here!

“I’ve gone through all of the editorial feedback you’ve provided for both books and I am super pleased… you’ve made my writing much stronger. I love your reports, by the way, that’s a really nice way to identify the bigger, more recurring issues and I particularly liked the comments on style, which were particularly useful and insightful. Delighted you got recommended to me.”

Stuart White, YA fantasy author

“I’ve always been a proud pantser when writing my first drafts. I didn’t believe in outlining or plotting because I thought it’d hamper my creativity. When I participated in the plot graphing workshop, I was hoping to glean a few tips, but I ended up loving the process of laying out plot, characters, and conflicts. I used the plot graph to map out my newest Work in Progress, and not only has it helped me write faster with more sense of clarity, it’s also allowed me to maintain my creativity. Now I’m a proud plotter!”

Kat Abbott, MG humor and horror author

“Mercer’s in-line commentary was enlightening… Never once were her comments condescending – all of her feedback was honest and straightforward and given in the spirit of truly wanting my manuscript to be the best it could be. She’s professional in all her communications. She always let me know where she was in the process and gave estimates of when she’d be finished, and was generous in her availability to answer questions or talk through some of her ideas. I hope to work with her again on a future manuscript.”

Danielle Simonelli, YA fantasy author


I’ve been feet first in this industry for over ten years, have interned at a publishing company where I read submissions and wrote Revise & Resubmit reports, attended numerous conferences – both regional and national, and organized a craft webinar for the local SCBWI that reached into 22 states and 3 countries. In addition to that, my personal work has received Moonbeam and Readers’ Favorite awards. Follow me @jmerceredits for a taste, where I post daily prompts for setting and character work, plot development, drafting, and revising.

Worried we’re not the right fit?

For $50, you can send me your first 25 pages for a sample edit (line and developmental thoughts, as best I can do with only 25 pages), which will be deducted off your total if you book a developmental plus or line edit overview.
