Jillian Manning – Editor

I love reading and writing (but not arithmetic)! After a decade in publishing, I am now a freelance editor for children's books.

Overview

Hello! Jillian here (she/her). I am a former YA and children's acquisitions editor now working as a freelancer. I have edited books for award-winning and bestselling authors, as well as renowned athletes and celebrities. But my favorite manuscripts are from talented, emerging writers ready to start an amazing career.


I have worked for Sourcebooks (imprints: Jabberwocky and Fire) and HarperCollins (imprints: Blink and Zonderkidz). I've had the honor to edit authors like Kwame Alexander, Zoraida Cordova, Rin Chupeco, Cory McCarthy, Miranda Kenneally, Allison Gervais, and many more.


I currently offer developmental (macro) editing, copyediting, and proofreading services for picture books. I also offer query letter reviews for young adult, middle grade, and picture books.


As far as an editing ethos goes, I love my Chicago Manual of Style and will wield it, but I defer to the importance of voice, especially when writing for young people.


Finally, I am also the author of five books with Sourcebooks and Sesame Workshop under the pen name Lillian Jaine, and I have ghostwritten several other books. Being an author helps me know the publishing process inside and out to provide you with the best possible service.


Please note: I am NOT a fit for horror, urban/paranormal fantasy, or religious work.

Working with Jillian was the best! She helped me through a very challenging project, which is a second edition of a book that I have already published. I am so pleased with the result! She is extremely detail-oriented and a very positive person to work with – I look forward to working with her on future projects! Thanks, Jillian!

Jillian edited my first children’s book! She was very professional, prompt with feedback and communicated clearly and regularly throughout the process. Her feedback was thoughtful and helpful and she was quick to answer any questions I had.

Jillian was great to work with as a new author! She gave me helpful information, great suggestions, and clear explanations of what she has edited. Jillian even completed the edited manuscript earlier than the proposed deadline. I would definitely recommend her to anyone new to children’s literature.
