Jessica MacLeish – Editor

I'm an editor and writer with 10+ years of editorial experience in the publishing industry, specializing in children's and YA fiction.


I'm a writer, editor, and storyteller with 10+ years of professional experience in the publishing industry. I'm passionate about storytelling in all forms, and I know a good story when I see one—and how to make it better if it's not quite working yet. I've written and published two guided journals (Celebrate Today: 365 Ways to Make Every Day A Holiday with Abrams Noterie in September 2018 and You've Got This!: A Creative Guide to Powering Your Happy with Popsugar/Scholastic in August 2021). In both my editing and writing careers, I have focused on youth media and pop culture.

The books I've worked on over the course of my career have been award-winners and bestsellers; received numerous starred reviews; appeared on various "Best of Year" lists; received awards; and been chosen as JLG selections.

I offer a variety of editorial services, including in-depth manuscript critiques (involving a comprehensive editorial letter) and/or line editing for either full manuscripts or first pages; query letter critiques; synopsis/proposal critiques; reader's reports (for publishers and agents); copywriting; and more. Send me a message to discuss what option is right for you and pricing/timing.

Jessica was a joy to work with! I hired her for Copy Editing and Editorial Assessment for a children's manuscript in which she provided very clear and concise feedback. She is very responsive and answers emails within a day or two. I recommend her 100%!

Jessica was an absolute pleasure to work with. She provided clear, constructive feedback of my first novel, with guidance on areas that needed the most work. Would work with her again, and highly recommend her to other writers!
