Hire the best horror developmental editors

Do you know what’ll send a shiver down your spine more than any horror book? Avoidable mistakes tainting readers’ views of your work and distracting from the story you want to tell. If you felt the hairs on the back of your neck rise at the thought, don’t worry. There’s a way to save yourself: hire a horror book developmental editor.

They’ll analyze your horror book to identify (and fix) issues with your pacing, structure, and character building. While changing large aspects of something you’ve spent hours working on might haunt you at first at first, these large-scale rewrites are a literary life saver.

You’ll want to hire a developmental editor with specialism in horror books, who won’t be spooked by genre nuances — and we’ve got your back. The Reedsy Marketplace is home to the top editors in the industry, who’ve worked with bestselling horror authors like Stephen King, so you can always trust their expertise. What are you afraid of?
