Helen Jennings – Editor

Friendly and experienced editor of contemporary, historical and YA fiction, working with you to bring out the best in your manuscript.

Overview

I’m a copyeditor, line editor and proofreader with a solid publishing background, primarily in commercial fiction. With more than two decades’ editorial experience, both in-house and freelance, I aim to strengthen your writing while preserving your unique voice.

I've worked on a wide range of fiction, including contemporary and historical titles as well as children’s and YA books. I have a strong eye for clarity, consistency and narrative flow, and authors I work with can expect thoughtful editing, clear communication and a collaborative approach throughout.

Alongside my editorial work, I also translate from German into English and have translated children’s fiction for publication.
