Editor & Writer


Marissa van Uden is an editor, a writer, and a semi-feral woodswitch who befriends all the animals. She grew up in Aotearoa-New Zealand, spent many years in Munich, Berlin and Los Angeles, and now lives in rural Vermont, in a cabin in the woods. She loves wild nature, Weird horror, and salty licorice. Her fiction has been published in Dark Matter Magazine (2022), Zero Dark Thirty (Dark Matter Ink, 2022), the Los Suelos anthology (Surface Dwellers, 2022), and Vastarien (2023). She is an anthologist (editor of Strange Libations: Dark Cocktails and the forthcoming Strange Machines: Dark Manuals (Apex Books) and The Off-Season: An Anthology of Coastal New Weird (Dark Matter Ink). She’s also an acquisitions editor for Dark Matter Ink and head of acquisitions at Apex Books, and an active member of the Horror Writer’s Association and Editorial Freelancer’s Association.


Marissa is a consummate and talented editor, always challenging me to look at my own work with fresh eyes and think again how to make it better. I attribute much of my growth as a writer in the last two years to working with her, and I count it a privilege to have had that opportunity. I cannot recommend her enough.

IN THE COMPANY OF THE DEAD (Pinnacle Award Winner for Best Fantasy)

Marissa is a fantastic editor. … Her line edits are some of the best I’ve seen. I highly recommend her.

THE SCORPION GAME (Quarter Finalist for the Amazon Breakthrough Novel Award)

Marissa has reset my bar for creative collaborators. From the firm guiding hand, to the side conversations about literature, to the different points of view she was able to get me to look at my own work, our time together was invaluable.

THE CASQUETTE GIRLS (Amazon Kindle #1 Bestseller, Publishers Weekly Starred)

It’s kind of creepy, how you get in my head and know what I mean even when I write it badly. Some authors I know resent the edit process, but it felt empowering to share the vision with you. I learned more during these edit sessions about my own weaknesses and how a reader views my words than I have in any other experience.

Your work is extraordinary. I can’t even begin to enumerate what I like about it. It’s all wonderful.

Bayard West


Working with Marissa as a developmental editor was a wonderful experience from start to finish. She identified story issues that had escaped both me and my critique partners and made her suggestions with such insight and enthusiasm that I was left energized rather than anxious about the revisions ahead. I have no doubt my book is much stronger thanks to her guidance. Can’t wait to work with her again!

A MORTAL SONG (Amazon Kindle #1 Bestseller 2016)


Fantasy tastes of habaneros and honey…

I stumbled across this beautiful quote by GRRM on why he writes fantasy - how great is this? It so perfectly captures my love for fantasy, science fiction and all its wild colors. We fantasy readers are the children who dreamed of hunting the forests at night and...
