Jack Renninson – Editor

Positive, professional editor of science fiction and fantasy, including New York Times and Sunday Times bestsellers.


Hi! And thanks for checking out my profile.

I am an experienced fiction editor, recently turned freelance after six years with major publishers in the UK. I work collaboratively with authors of all experience levels to make their stories shine and to help them achieve their publishing goals.


My priority is bringing the novel of your dreams onto the page and into the hands of readers. That means:

— Careful reading, focussed on understanding the heart of your story
Detailed analysis of how your writing works and how it will impact its audience
Encouraging feedback, guiding you toward your own solutions

If this is what you might need, please don't hesitate to get in touch.


Before turning freelance, I worked as Editor at HarperCollins, commissioning and publishing on the HarperVoyager science fiction and fantasy imprint. Authors I have worked with include George R.R. Martin, Robin Hobb, and Jay Kristoff. I was the UK lead editor for writers including Sunday Times bestseller Kate Heartfield, New York Times bestselling geek superstar Wil Wheaton, and acclaimed new voices such as Sue Burke, David Wragg, and Anna Stephens.

While my experience is deepest in SFF, I have edited titles across many genres over the years: crime and thriller, horror, history, memoir, cookery, health.


'Jack is a top-class communicator who couples creative vision with a profound grasp of the craft of storytelling. Working with him is an unbridled joy'
David Wragg, author of THE BLACK HAWKS

'I honestly can't say enough about what a joy and privilege it was to work with Jack on THE EMBROIDERED BOOK. It's so much better for it, and I'm a better writer for it'

I only regret having had only a single novel to ask for Jack’s help with! I could not have asked for a better editor and have enjoyed our brief but productive relationship during which he performed a structural edit on my first novel. Jack is very personable and has been as supportive as he has been incisive about pointing out the opportunities to strengthen the story and characters as they wer...
