Ceileigh Mangalam – Editor

Vancouver-based editor of genre fiction: fantasy, sci-fi, horror, and romance.

Overview

I've been a freelance editor in Vancouver for ten years, specializing in structural/developmental editing for fiction, though I also provide copy and line editing services. Primarily, I like to work on contemporary fiction and fantasy, but I'm also looking for fresh sci-fi, horror, and romance narratives. Send me your genre fiction novels; I'd love to work on them with you!

I don't use any AI services in my editing, and I prefer not to work on AI-generated text. My favourite projects are consistently from creatives who conceive, write, and edit their work without AI assistance. That said, if you're curious about working with me and wondering if your AI usage "counts," feel free to get in touch.

Ceileigh delivered exactly the kind of conceptual editing I was looking for. Lots of things I was too close to the project to catch, lots of things I half-noticed but didn't act on until she caught them, too, (and lots of comments that simply made me feel seen as a writer). I'll likely hire her f...

Ceileigh was an absolute pleasure to collaborate with; she went above and beyond, and her notes ended up going into more depth than I expected, which is great. She made sure to explain why certain things aren't working and gave concrete but broad enough suggestions on how to fix certain things th...

Ceileigh has been incredible to work with! She took the time to understand what I was trying to accomplish with the story (and the books that will follow) to make sure they will tie together. Her developmental edit shed light on things I had missed touching on, suggestions on how to improve the i...

This is my second time working with Ceileigh, and as always it was great. She helped me with my second book from start to finish through three rounds of edits and I know my work is all the better for it. She has a keen eye!

Some of the suggestions made are/were actionable. And helpful ultimately, because now I know what a casual reader might get out of the story. In all fairness, this was a companion piece and I asked her to edit it knowing that she has never read the debut novel. So a LOT of the context was missin...
