Heather Martin – Editor

I'm a copy editor with years of in-house and freelance experience. I've worked on hundreds of novels, and I hope yours will be next!

Overview

Hi, I'm Heather, a seasoned copy editor with years of experience in the publishing industry. I've worked in house with two of Canada's largest publishers, Harlequin Books and Nelson Education, and have years of freelance experience, working both for publishers and directly with authors.

I specialize in YA, romance and thrillers but love to work across all genres. I've copy edited everything from novels and manga to trade nonfiction and scholarly monographs. I've volunteered my copy editing skills to non-profit organizations over the years as well.

I'm here to help keep your readers immersed in your book. They'll slip right past tidy grammar and spelling and into your story, where they'll always know who's speaking to whom, be confident that one can indeed drive from New York City to Montreal on the I-87, and hear your characters' voices speaking right to them from the page.

I have a reputation for accuracy and attention to detail when it comes to house style, grammar and storyline consistency. But just as important, I'm known for preserving the author's voice, providing clear explanations for suggested changes and meeting deadlines without fail.

If your book is ready for that next step, I hope you'll reach out!

Testimonials from authors:

I’ve worked with a lot of copy editors over a lot of years and come to appreciate that copy editing is a science and an art. The ideal copy edit is rigorous but not prescriptive. It's a tough balance to strike, but Heather does. She manages to be thorough but not intrusive, to not only make corrections, but to help the manuscript become a better version of itself.

—Jenny Holiday, USA Today bestselling author of Undue Influence

Not only were the punctuation and spelling mistakes immaculately cleaned up, but Heather went way beyond my expectations. She tracked the novel’s timeline, pointing out places where it was off, she noticed minute details in early chapters that appeared differently in subsequent chapters, she even noticed geographic errors in my African setting. Further, she read the work deeply enough to be able to point out places where characters were acting in ways that seemed inconsistent with their personalities. These are mistakes that readers would have noticed and been distracted by. Mistakes I’m grateful won’t appear in the published book because ultimately, they’d reflect on me. In short, Heather took the manuscript and polished it beautifully. Her name won’t appear on the cover, but make no mistake, she was a critical contributor!

—Adrienne Benson, author of The Brightest Sun

Heather undertook the copy edit of my novel and from the outset, I was impressed by her professionalism and assessment of the parameters of the project. Her edits showed a clear grasp of the intended audience, and in her handling of the text, she combined thoroughness and attention to detail with a light, unobtrusive touch…Heather was an absolute pleasure to work with and I would work with her again in a heartbeat!

—Claire Horsnell, author of The Crowsbrook Chronicles Series
