Hannah Gramson – Editor

Kind, professional, and thorough copy editor with 7+ years of experience, specializing in historical fiction, rom-coms, and mysteries.

Overview

I’ve been a freelance copy editor and proofreader for over 6 years, working with independent authors and publishing houses, including Penguin Random House and Scholastic. I specialize in romantic comedies, mysteries/thrillers, historical fiction, and fantasy for middle grade, YA, and adult audiences.

I’m passionate about helping authors polish their prose and produce the best version of their story. As a copy editor, I correct grammar, punctuation, and spelling errors to enhance readability, all while preserving your unique voice! I’ll also flag story inconsistencies and perform fact-checking the accuracy of real names, places, dates, and other facts. I provide a comprehensive style sheet to help maintain consistency in both style and content throughout the manuscript. My goal is to bring out the best in your story while making the editing process seamless and enjoyable!

Hannah Gramson added a touch of magic to my words and deserves an award for proper comma usage. She met my absurdly quick deadline with grace. I will definitely work with her again.
