Katherine Locke – Editor

I'm a passionate, committed editor who loves working with authors at every stage of their writing journey—whether you're polishing your first book or leveling up your twentieth. I specialize in developmental editing, helping writers strengthen story structure, deepen character arcs, and refine prose. My clients have gone on to self-publish and traditionally publish, including with Big Five publishers like HarperCollins, Penguin Random House, and Hachette.

What sets me apart? I don't impose my vision onto your story—I help you bring your vision to life. If you're still figuring out what that vision is, no problem! We’ll work together to uncover it and bring it into focus.

As a developmental editor, I’m especially drawn to shaping tighter, more logical plots, smoothing pacing, and helping characters come alive on the page. I love connecting the dots between worldbuilding, character, and plot to make the whole story shine.

I specialize in young adult, middle grade, and romance novels. Every project includes detailed in-manuscript feedback, a comprehensive edit letter, and (for most clients) a follow-up video call to talk through next steps and revision plans. I’ve found that call to be a game-changer—it's often where breakthroughs happen.

Editing, to me, is like solving a great puzzle. There’s nothing more satisfying than helping a stuck story snap into place. If you're feeling overwhelmed, uncertain, or simply want to take your manuscript to the next level, I'm here to help. I can't wait to work with you.

I have worked with Katherine on multiple manuscripts, and each time she has gone above and beyond to help get my novels into querying-shape. I learned so much from her feedback, and truly would not be the writer I am today without her insight. It’s clear that she is passionate not only about editing, but about helping her clients to unlock their full story-telling potential. - Sabrina Kleckner, author of The Art of Running Away
