Psychological Thriller Co-Writer

Write the Next Bestselling Psychological Thriller with Mary Stone! A Rare Opportunity for a Talented Cowriter to Brand Themselves with a Bestselling Author Are you obsessed with psychological thrillers—the kind that leave readers breathless, flipping pages deep into the night? Do you have a knack for crafting mind-bending twists, unreliable narrators, and tension so thick it lingers long after the final page? If so, we want to offer you a rare opportunity to co-write alongside one of the most recognized names in the genre. Mary Stone Publishing is looking for a highly skilled and creative cowriter to collaborate on standalone psychological thrillers novels each month. This isn’t just a writing gig—it’s a chance to establish your name in a bestselling brand, work with industry-level editors, and reach thousands of devoted psychological thriller fans. This is a long-term, remote position that gives you the freedom to work on your own schedule—as long as deadlines are met, communication stays sharp, and quality remains top-notch. The perfect fit? Someone with a deep understanding of the psychological thriller genre—from gripping suspense and complex character arcs to jaw-dropping reveals. If you have a sharp analytical mind, a passion for dark and twisted storytelling, and the ability to elevate a story to its full potential, this could be the career move you’ve been waiting for. Scope of Work: Bring Psychological Thrillers to Life As a cowriter for Mary Stone Publishing, you will collaborate closely with your assigned Developmental Editor (DE) and other team members using our online platform. You’ll follow a detailed series and book outline, allowing you to bring your storytelling skills to an established framework while adding your unique voice. To ensure a smooth transition to our process, you’ll receive comprehensive training on our distinctive style, expectations, and workflow.

• Creative Execution: We provide detailed series and book outlines to serve as the foundation of each novel. You’ll have the opportunity to read the outline in advance and discuss it with the team before writing begins. While the structure, major twists, and story arc are predetermined, you’ll have creative freedom to bring scenes and characters to life in an immersive and compelling way. Your work should be self-edited and proofread before submission to maintain a high-quality draft.
• Critiques & Feedback: Each novel will be approximately 80,000 words, and you’ll submit to your DE in four 20,000-word sections for review. This staged submission process allows major structural, pacing, or character issues to be identified early, preventing the need for extensive rewrites later. Your DE will provide detailed critiques and feedback at each stage, helping to refine psychological depth, suspense, pacing, and character motivations. This iterative approach ensures the story stays tight, immersive, and well-structured, giving you the opportunity to adjust and strengthen the manuscript as you progress.
• Substantive Editing & Revisions: Once the full manuscript is completed, it will undergo a substantive editing pass by the DE. This is a deep revision process focusing on narrative cohesion, tension, character development, and psychological complexity. The book is not considered complete until you have implemented the required revisions to the editor’s satisfaction, ensuring the manuscript meets MSP’s high storytelling and quality standards.
• Multi-Stage Editing & Final Revisions: After the developmental editing phase, the manuscript will move through our multi-stage editing and revision process, which includes line editing, copy editing, style editing, and a final quality control pass. Each stage refines different aspects of the book—from sentence structure and clarity to grammar, consistency, and final polish. After each editing pass, you will complete any requested revisions to further refine the manuscript.
• Maintaining Character & Series Continuity: With the support of your developmental editor, you’ll reference and update the Master Character List within each series outline to track key details about each character. This includes motivations, traumas, mental states, physical attributes, behavioral patterns, and relationships. The MCL serves as a living document that keeps characters psychologically authentic and prevents contradictions across a book or series. By maintaining this list, you’ll ensure that a character’s decisions, emotional responses, and backstory remain believable and consistent, enhancing the realism and depth of the story.
• Communication: Must possess excellent communication skills, as communicating with us for deadlines is a must. The candidate will need to be willing to adapt to our style and work independently while at the same time being open to revisions and suggestions. We work as a team and care about our writers, editors, and team. The team will be there to provide help and suggestions where needed.
• Technical Proficiency: Demonstrate proficiency with Microsoft Word’s track changes and commenting system, and adhere to the Chicago Manual of Style, Mary Stone Publishing Style (to be provided), and standard U.S. English conventions.
