Luna Soo

Luna Soo – Editor

Editor of award-winning novels for middle-grade and young adult readers, specialising in thoughtful developmental editing and copyediting.

Overview

With a decade of in-house experience at Hardie Grant Children's Publishing, I'm excited to offer you my skills as a freelance editor. I focus on middle-grade fiction (for readers aged 9-12) and young adult fiction (for readers aged 13+), and I've worked on everything from contemporary YA fiction to MG fantasy-adventure. Many of the novels I've edited have won awards. Yours could be next!

My aim, always, is to help writers tell their story in the best way possible. I edit with both the writer and their readers in mind, which involves constructive feedback on the entire manuscript as well as close, careful copyediting to ensure every sentence shines.

As a developmental editor, I provide written feedback on various 'big picture' aspects of a novel such as pace, plot and character development, and offer suggestions for how to make your story even more gripping and dramatic. If you're stuck for ideas or have written yourself into a corner, I'm happy to discuss ways to move forward; I'm keen to help you find out what works for both you and your story.

As a copyeditor, I tend to leave lots of comments in the margins, from 'This isn't quite in your character's voice, can you please rephrase?' to 'You've created such a tense atmosphere here, well done!' This approach empowers you to improve your manuscript while also helping you hone your craft as a writer.

'Luna is a bona fide story genius who always knows exactly what the narrative needs to lift it to the next level. My books are undoubtedly much better for her input, and I am a better writer for having worked with her. I recommend her unreservedly.' – Sarah Armstrong, award-winning author of 'Run'.

If you want to take your novel to the next level, I'd love to work with you!

Work experience

Self-employed

Jul, 2026 — Present
As a trusted freelance editor, I've edited middle-grade fantasy-adventure, memoir and picture books with a focus on helping each author elevate their story to create a truly gripping read. I love working on novels with unique voices that offer readers a fresh perspective on the world. I'm particularly interested in working on contemporary fiction for kids, teens or adults, especially those written by authors with diverse backgrounds.

Nov, 2016 — Jun, 2026 (over 9 years)
I worked closely with debut and established authors to develop and finesse their novels for middle-grade and young adult readers. I loved doing developmental edits and copyedits in genres including contemporary fiction, coming-of-age, fantasy, adventure and romance, and particularly enjoyed providing authors with clear, constructive feedback and encouragement throughout the entire editorial process. I'm thrilled that many of the novels I edited by beloved authors such as Jeremy Lachlan, Biffy James, Erin Gough and Sarah Armstrong have been published internationally and won multiple awards. I'm also proud to have edited early readers such as the 'School of Monsters' and 'Billie B Brown' series by Australian Children's Laureate Sally Rippin, along with picture books in the 'Claris' series by bestselling author-illustrator Megan Hess.
