Greg Cox – Editor

Greg has worked as an editor for Tor Books and William Morrow. He specializes in science fiction, fantasy, and horror.

Overview

I've been a professional science fiction, fantasy, and horror editor for more than thirty years, working with such celebrated authors as Jonathan Maberry, Seanan McGuire, Richard Matheson, Harry Harrison, Chelsea Quinn Yarbro, Graham Joyce, Rosemary Edghill, and others, as well as any number of new and beginning authors. I've worked both full-time and as a consultant for Tor Books, and enjoy working with authors on a developmental level to help their manuscripts achieve their full potential, making the best parts better while also pointing out any issues that need to be addressed in the most encouraging way possible. As a lifelong fan of all things weird and fantastic, I like nothing better than to dive deep into intriguing new realms of the imagination in order to help authors fully realize their creative visions.

I'm also a New York Times bestselling writer, and I like to think that working both sides of the desk makes me a better editor since I know what it's like to have my own work edited with care.

Work experience

Tor Books

Jan, 1998 — Present
After working full-time at Tor Books for many years, I elected to become a Consulting Editor because my writing career was taking off in a big way. As a Consultant, I continue to acquire and edit special projects for Tor, while also doing the freelance editing I enjoy for other authors and publishers.

Tor Books

Jun, 1990 — Jan, 1998 (over 7 years)
As a full-time science fiction, fantasy, and horror editor, I worked with such noted authors as Jonathan Maberry, Seanan McGuire, Richard Matheson, Poul Anderson, Chelsea Quinn Yarbro, and others, as well as acquiring and editing media-tie books based on such popular series as Mortal Kombat, Nightmare on Elm Street, and Farscape.

Arbor House/William Morrow

May, 1987 — Jun, 1990 (about 3 years)
Working as an assistant editor at Arbor House was a great education in commercial publishing.

Greg asked the right questions, called out where I was being lazy, and pushed always for clarity and immersion. The piece is stronger for the work he has done on it, and I am very grateful for it.
