Celia Chalfoun – Editor

Science fiction and fantasy editor with a strong focus on World building, Character development, Symbolism, and Incluing. English/French.


If you're a science fiction or fantasy writer looking for an editorial assessment or/and a developmental edit, you're in the right place! In my work, I emphasize elements that are crucial in creating a story with strong foundations: World building, Character development, Symbolism, and Incluing (the subtle weaving of information into the story). I love diving deep into a manuscript, feeling the world you created, and coming back out with as much insight as I can.

I’ve been lucky to work with over 20 authors here on Reedsy and many more in different capacities. Whether writing is still new to you and you’re looking to develop your craft or you’re a more experienced author, I can help! As a writer myself, I understand the work that comes with the craft, and I will focus my time and energy on helping you take your story to the next level. After all, science fiction and fantasy are all about exploring new horizons and new ideas!

I strive to provide:

- helpful, detailed comments and suggestions;

- clear guidance while respecting your voice and working on what makes you unique;

- a strong focus on world building: shortcuts, simplistic social descriptions, inconsistencies that affect the plot… Every manuscript has its issues and after so much time spent writing it, it’s perfectly normal if you stop noticing them. We all need to take a step back once in a while!

- help through a tool called mind-mapping: I love to draw diagrams. They reveal so much about the inherent structure of a story, the movements between characters and events, and the symbols that keep on showing up;

- an attention to the narrator’s voice and its related issues: does your story need one or several viewpoints? Does the narrator's voice shift within the story, without any apparent reason? Through a misuse of the narrator’s voice, are you infodumping and/or can we improve the incluing?

Please don't hesitate to reach out with any question! I'm always happy to chat.

Celia has been a pleasure to work with. It was obvious to me that she understood what my story was about and helped me work out parts that were confusing, underdeveloped, or missing. Her willingness to collaborate on-going is inspiring. I can’t wait to begin making my manuscript better, because of her feedback.
