Editorial Services

I offer freelance editing for YA and MG fiction (no short stories, graphic novels, or nonfiction, please). I pride myself on my attention to detail and structure alike, as well as my accessibility and friendliness. I’m always happy to answer questions about my editorial suggestions or help brainstorm plans of attack for no extra cost. I will push you to make your materials the best they can be without encroaching on your vision.

Here’s some information about me:

  • I’m a YA writer represented by Heather Flaherty at The Bent Agency.
  • I currently intern at Writers House.
  • Before Writers House, I interned at Stonesong, Entangled Publishing, and a literary agency I can’t publicly name for a combined total of two and a half years.
  • I’m a volunteer with Beth Phelan’s #DVPit, where I offer free pitch critiques for entrants.
  • I’ve edited for authors who have gone on to sign with agents and sell their manuscripts to publishers.
  • I’m happy to work directly with a writer or with their agent or editor.

My services, pricing, and contact form are below. Please do get in touch with me at markobrienbooks AT gmail DOT com if you have any questions. I can’t wait to work with you!

What I offer:

Query edit: $15 (one round; any additional rounds are $5)

What I’ll do: Edit everything from structure and format to diction and punctuation. Offer a thorough critique pointing out areas that need improvement and writing long strings of exclamation points when I love something. Make sure every word counts—and shines.

Submission package: $30 (one round; any additional rounds are $15)

What I’ll do: Edit your query and the first thirty pages of your manuscript (roughly 7,500 words). Agents often want sample pages included with the query, and it’s vital that your opening pages draw them in. I’ll help ensure your pages are the best they can be.

Reader’s report: $0.003/word (for example, $150 for 50,000 words)

What I’ll do: Drawing upon my two and a half years of experience writing these for agents and editors, I’ll review your full manuscript and write a reader’s report (two pages minimum). This will break down what works in your manuscript, what doesn’t, and how to improve.

Full manuscript line edit: $0.006/word (for example, $300 for 50,000 words)

What I’ll do: Review your full manuscript, leaving suggestions, questions, and hearts via Microsoft Word’s track changes. Note every problem area I find on a line-level scale and suggest how to fix them. Ensure you walk away happy with your manuscript.

Full manuscript developmental edit: $0.007/word (for example, $350 for 50,000 words)

What I’ll do: Review your full manuscript with an eye for the big-picture problem areas. If you’re concerned about elements like pacing, character, and plot, this is the option for you! I’ll leave notes in the manuscript in track changes in addition to writing you a comprehensive edit letter.


Please submit your initial information through the form below, or email me at markobrienbooks AT gmail DOT com.

Please be sure to include your manuscript’s word count and a summary, whether a query letter or a short pitch.

*Note: I cannot guarantee you will sign with an agent or be offered a contract with a publishing house as a result of receiving and incorporating my edits.
