Harriet Moulds – Editor

As an editor and publisher, I understand what it takes to turn a manuscript into a book that readers will love and retailers want to stock.

Overview

Editor and publisher. After years developing and editing licensed Disney and Marvel titles at Autumn Publishing, an imprint of Bonnier Books, I launched the SparkPool Publishing imprint, which now publishes around 40 books annually across YA, lifestyle, puzzle, and gift.

I have over 10 years experience in publishing. Working on both sides of the publishing process has given me a unique perspective. I don't just look at manuscripts through an editorial lens, I understand the commercial realities of publishing and what helps a book succeed in today's market.

I offer developmental editing, editorial assessments, copy editing, and proofreading for authors seeking professional, actionable feedback and meticulous attention to detail.
