Lizzie Sitton

Lizzie Sitton – Editor

I’m an experienced editor of internationally acclaimed children’s books with a career spanning two decades in the industry.

Overview

I am a developmental editor with 20 years of experience specializing in picture books, early readers, illustrated middle grade fiction and graphic novels.

As a developmental editor, initially I provide my clients with detailed feedback on the structure, clarity, and tone of their work with suggestions for revision as well as line by line edits and notes within the manuscript.

As a line editor, I polish final drafts with a focus on consistency, style and tone.

Within the fiction team at Walker Books, I edited funny illustrated character-led fiction, including the Julius Zebra series by Gary Northfield, translated into 18 languages worldwide; They Didn’t Teach THIS in Worm School by Simone Lia, translated into 12 languages worldwide and graphic novel adaptations of the renowned Alex Rider series by Anthony Horowitz.

Having also worked for ten years within the prestigious Walker picture books department, I was the long-standing editor of many successful authors including Bob Graham, Atinuke, Daisy Hirst, Smriti Halls, Laura Dockrill and Oliver Jeffers to name just a few.

I have an encouraging, collaborative style, and will work with my clients step by step to develop their unique ideas and voice, while offering gentle suggestions for ways they might consider shaping and plotting their story so that it truly sings and resonates with readers in the best way possible.

I am particularly interested to work on picture book projects for readers of 0 to 5 years and young illustrated fiction for readers of 7 to 11 years.

“Lizzie was the editor of my first novel for children and working with her exceeded all of my expectations. Not only was she a brilliant editor with insights and creative suggestions that improved the structure and plot of my book but in an unassuming way she also wore the hat of teacher and mentor. She patiently helped me to find my voice as a writer. Lizzie was super committed with an absolute belief that the books we were working on would be a success. Having a childhood dream of writing a novel come into fruition in my 40s gave me a great boost of confidence to believe that anything is possible. I’m so so grateful to Lizzie for this.

If you’re looking for a really smart editor who is insightful, an absolute joy to work with and has the ability to bring out the best writer in you, I thoroughly recommend Lizzie.” Simone Lia, author and illustrator of They Didn’t Teach THIS in Worm School!

“I always feel my work is in safe hands with Lizzie. She always grasps what my stories are about - even when I'm not totally clear about it myself. And she come up with brilliant ideas that improve them no end - ideas consistent with my style of writing. She intuitively knows how a story will land for a reader - or listener. Lizzie knows how to make a story sing.” Atinuke, author of Baby Goes to Market

Work experience

Walker Books Ltd

Feb, 2009 — Sep, 2023 (over 14 years)
During my fifteen years working with the team at Walker Books, I hugely enjoyed nurturing talent and developing strong creative relationships to help build a diverse list of distinguished, trail-blazing, award-winning and best-selling board books, picture books, humorous young illustrated fiction, illustrated teen and YA fiction, graphic novels and biography. Some of the wonderful projects I worked on include the UK editions of Town Is By the Sea by Joanne Schwartz and Sydney Smith and Small in the City by Sydney Smith - both winners of the Kate Greenaway Medal; A Child of Books by Sam Winston and Oliver Jeffers which was translated into over 40 languages worldwide and chosen as the winner of the Bologna Ragazzi Prize; Inch and Grub by Alastair Chisholm and David Roberts winner of the Scottish Booktrust Book Prize; Grey by Laura Dockrill and Lauren Child selected by Waterstones as a must read for 2024.

Bloomsbury Publishing Plc

I was responsible for commissioning, project managing, copyediting, and proofreading within the children’s books department where I developed a passion for graphic novels and comics. Among the books I acquired for the Bloomsbury list was a groundbreaking, interactive and immersive teen novel called Cathy’s Book by Sean Stewart and Jordan Weismann which was selected as a Waterstones Book of the Month and received exceptional critical acclaim.

Lizzie was a pleasure to work with particularly as this was my first book project. Lizzie took my dry style of text and turned it into a real children's book which, when it was read out, sounded great. Feedback from trial readers has been positive so far so I think a good job has been done. Tha...

This is the third time I have used Lizzie. My PB was a totally different story to the first two I had sent her. She was able to work her editorial magic by suggesting that the story be written in the first person and showed how to rework the structure. Her feedback and editorial suggestions are ...

Lizzie had worked on my first PB in a potential series and had total editorial vision of what I was trying to achieve with the first story. So it was a no-brainer to ask her to edit my second book. She worked her magic again. Lizzie offers professional and supportive feedback, with detailed edito...

When I approached Reedsy, I had really no idea what to expect. I thought that since it is such a large organization, I might find it intimidating to use. However, I found the opposite to be the case. Although Lizzie is indeed very professional and very serious and thorough in her evaluations, she...
