Moonless Publishing Group partners with writers from blank page to bookshelf — offering ghostwriting, editorial development, self-publishing assistance, marketing, and book-to-script adaptation under one roof.
Moonless Publishing Group was founded in 2026 to do something the traditional industry has stopped doing well: take a writer from idea to finished book — and then make sure the book reaches the readers it deserves.
We work across the full publishing lifecycle. We ghostwrite for clients who have a story but not the time. We develop manuscripts editorially. We guide independent authors through the realities of self-publishing. We design covers, build marketing campaigns, and adapt finished books into scripts for film and television.
As an imprint of SteelHorn Holdings, we bring the resources of a long-view backer and the responsiveness of an independent house. Our doors are open to first-time writers and seasoned authors alike.
Every stage of publishing, handled in-house with one consistent team.
Fair terms, transparent process, and respect for the writer's voice.
Books, ebooks, audio, and scripts — built for the way readers live now.
The independence of a boutique press with the resources of a parent company.
Six core services covering the full arc of a book — from the first conversation about an idea to the final adaptation for screen.
You have the story, the expertise, or the life. We have the writers. Our ghostwriting team works confidentially with executives, public figures, founders, and private clients to produce manuscripts that read like the author wrote them — because, in every way that matters, they did.
Discuss a Project →Developmental editing, line editing, and copyediting from editors who have shaped bestsellers and debuts alike. We work with you on structure, voice, pacing, and prose — preserving what makes the book yours while strengthening what doesn't yet work.
Request an Evaluation →Selected manuscripts are acquired and published under the Moonless imprint with full editorial, design, production, distribution, and marketing support. We pay competitive advances, run open submissions, and read every query that meets our guidelines.
View Submission Guidelines →For authors who want to retain ownership, we offer a guided self-publishing path: cover design, interior layout, ISBN management, Amazon and IngramSpark setup, ebook conversion, and ongoing distribution support. You keep the rights. We handle the rest.
Start the Conversation →Launch strategy, pre-order campaigns, ARC programs, podcast and media outreach, paid advertising on Amazon and Meta, and ongoing visibility work after launch day. We treat marketing as part of the book — not an afterthought.
Plan a Launch →Through our partnership with the SteelHorn entertainment division, we adapt finished books into feature screenplays and limited-series formats. From option agreement to delivered draft, our writers and producers shepherd the project end-to-end.
Inquire About Adaptation →Not sure which service fits your project? We'll help you figure it out.
Schedule a ConsultationEach month we spotlight one title from the Moonless list — the book we most want in your hands right now.
A masterclass in slow-burn dread. — Advance Notice
On a cliffside in the north Atlantic, a recently widowed woman returns to a house that does not want to be returned to. A gothic suspense novel of inheritance, grief, and the bargains the living make with what refuses to go.

We accept open submissions year-round across all of our service categories — traditional acquisition, self-publishing partnerships, ghostwriting consultations, editorial development, and adaptation inquiries.
Whether you have a finished manuscript, a sample chapter, or simply a strong idea and a question about which path is right for you — we want to hear from you.
Send us a brief query — genre, length, premise, and where you are in the process. One page is plenty.
Attach the first three chapters (or your full proposal for nonfiction). Word documents or PDFs, please.
Every submission receives a personal reply within four to six weeks — no form rejections.
If we're a fit, we'll walk you through which service or publishing path makes the most sense for your project.
