Katie McGuire – Editor

Editor of fiction and nonfiction with a decade of experience in traditional print publishing and digital serialized storytelling.

Overview

For five of my six years with Pegasus, the company's crime imprint was my focus—I love a good mystery! I've worked on a number of subgenres, including neo-noir, more traditional mysteries, and cozy crime, and have had the pleasure of working with fantastic authors like Antony Johnston, William Boyle, S. J. Rozan, Paul Vidich, and Molly MacRae.


On the fiction side, I've also worked on a number of historical fiction projects and select graphic novels. No matter the genre, I'm open to both standalone projects and books in a series. In the nonfiction realm, I've worked on narrative history, biography/memoir, and true crime projects. You can see my full list of projects below.


For nearly two years after my time at Pegasus, I was the novel acquisitions lead and an original novels editor at Tapas Media, acquiring, developing, and editing serialized fiction mostly in the romance and fantasy genres. For two and a half years after that, I was an editor with the Quarto Group, working predominantly on illustrated nonfiction titles in the pop culture and entertainment categories for the Epic Ink imprint, as well as books on the b&m kids! and Wellfleet imprints. As of January 2025, I am open to freelance editorial work as I complete my MFA in Popular Fiction Writing & Publishing at Emerson College.


I'll read anything having to do with spies, royalty, or Hollywood, real or imagined, and, as an enormous comics nerd, I also enjoy a good superhero tale. I look forward to hearing your story!

Katie was able to diagnose the overall issue that was plaguing my work and pinpoint the places in the manuscript where it was an issue. She provided a comprehensive editorial letter and provided comments on the text itself. Other editors would have simply provided the letter and then leave you to figure out the rest on your own. I would work with Katie again!

I have worked with other editors before - Katie is a step above in terms of her standards and willingness to go the extra mile, despite my own shortcomings. She took my work to another level - There is no doubt about that statement. I am sorry to be done with her. I miss her enthusiasm and positivity. She made me feel like my writing was worthwhile and legitimate. Thank you, Katie,
