I love to help authors proofread and polish their work, and frequently do book reviews also. I have been co-author of 5 books in the spiritual genre. I am a magazine writer, editor and proofreader.I have two blogs, on books and new products. I write magazine articles about such topics as quirky and historical travel, animals, the psychic world, and unusual museums or destinations.The books I've co-authored have been with a famous psychic/medium/motivational speaker. I have also written and produced radio programs and lectures. I pay great attention to detail regarding grammar, punctuation, sentence structure and spelling. I pride myself on my proofreading and editing skills. I also do book reviews so am exposed frequently to books in their final form or pre-release form, where I often catch mistakes before the finished product goes to print.

Professional, punctual wordsmith and creative developer with great versatility and experience ranging from providing developmental edits and creative direction for a producer of the CREED movie franchise on his newest memoir, to the more grounded exercise of writing copy for real estate professionals. I provide story development to celebrity clientele from actors to musicians and producers, crafting pitches, treatments, and decks from visions scrawled on cocktail napkins. I also have extensive experience with script coverage and screenwriting––samples available privately. Advanced proficiency with Final Draft, inDesign, Illustrator, Photoshop (for clientele seeking full pitch decks as well as copy) and Word, Google Docs and Sheets.

I've worked professionally as an editor and writer for over eight years, providing clients with ghostwriting, developmental editing, copyediting, and proofreading. As an author myself, I understand how to work on a manuscript through a "big picture" lens to strengthen its narrative arc and themes, as well as how to work at the granular level of stylistics and copyediting. My experience as an editor ranges from nonfiction book manuscripts to graduate admissions essays to website copy. I specialize in memoir, personal narrative, oral history, and creative nonfiction. What stories do you have to tell? Who might be waiting to hear them? I believe that writing is a practice innate to all humans—you don’t need a publication credit to be a writer. But while we can all benefit from journaling and creative writing, it can feel daunting once we’re ready to share our writing with an audience. Good writing requires special attention to craft. My goal is to help you elevate your writing so that it better reflects your voice and communicates your stories. Here’s what I offer as an editor (though I’m open to working beyond this list): - Developmental editing, copyediting & proofreading: book manuscripts; admissions/scholarship essays; blog posts; narrative essays; and academic papers. - Regardless of your project's scope, I will give you feedback on how to improve your writing's structure and style. - My specialty is creative nonfiction: any writing that may fall under personal narrative, memoir, travel, social sciences, or long-form journalism. I am the published ghostwriter of a two-volume memoir. I also love writing about and studying climate change, geology, astronomy, mental health, and sustainability. Here’s what I offer as a ghostwriter: - Eulogies & obituaries: I can help you write a meaningful eulogy or obituary from scratch, or I can help you polish a draft you already started. Either way, I will work closely with you to tell your loved one’s story. Here’s what you get when we work together: - An annotated document explaining my edits: I genuinely care about teaching people how to write better so that eventually you won’t need to hire someone like me! I’ll include comments in your document explaining how to improve your grammar, word choice, and punctuation. - An editorial letter: If your writing needs more substantial revisions than copyediting and proofreading, I’ll include a short letter explaining what you can do to strengthen your arguments, structure, or style. - A writing coach: For writers who are balking at starting a long-term writing project, I can teach you how to manage your project so that you stay organized and inspired in your writing practice. We can review multiple drafts over a span of months so that you receive critical feedback throughout your writing process, not just on the final draft. Together we can elevate your next writing project. I look forward to reading your work! Sincerely, Sara Alura Rupp

I am a bestselling and award-winning author, editor, ghostwriter, and storyteller with multiple published books and years of experience helping clients bring powerful stories to life. My own novels have reached the top of Amazon bestseller lists, earned literary awards, and received praise from respected review organizations including Readers' Favorite, The Midwest Book Review, and Online Book Club. Beyond my own work, through ghostwriting and editing, I have helped authors develop, refine, and publish books across a wide range of genres and subjects. When ghostwriting, I work closely with clients to transform ideas, outlines, and rough concepts into compelling manuscripts that feel authentic to their voice and vision. Whether you're starting with a detailed plan or a single spark of inspiration, I can help shape it into a finished book. As far as editing, I offer both developmental editing and line editing services. Developmental editing focuses on the larger elements of storytelling and structure such as plot, pacing, character development, organization, theme, and reader engagement, while line editing refines the prose itself for clarity, flow, style, and impact. I have edited numerous books that have gone on to successful publication, helping authors strengthen both the foundation and execution of their work. My storytelling experience extends beyond books. I have worked on fiction and nonfiction projects, video game narratives, and stories across multiple creative mediums. Regardless of format, my focus remains the same: creating engaging experiences that connect with audiences and leave a lasting impression. Writing a book is a major undertaking. It requires time, patience, creativity, and careful planning. Many people have a story they want to tell but lack the time, experience, or confidence to bring it to the page. That's where I come in. Whether you need a ghostwriter, developmental editor, line editor, story consultant, or creative partner, I can help you turn your ideas into a polished and professional finished product.

Book Ghostwriter and Editor | Developmental Editing, Line Editing, Copy Editing, Amazon KDP Formatting I write, edit, and format fiction and nonfiction for Amazon KDP, from messy first draft to print-ready file. Most manuscripts that land in my inbox aren't broken. They're close. Chapters out of order, a middle that sags, a narrator who sounds like three different people. Usually the author can feel something's off but can't put a finger on it. That's the part I'm good at: finding the actual problem and fixing it without sanding off your voice. Recent work • A five-book steamy romance series. Line editing plus continuity tracking, because readers absolutely notice when a character's eye color changes in book three. • A psychological thriller where the twist showed up too early. Moved the reveal and tightened the last third. • A nonfiction leadership book built from interview transcripts and voice notes. Ghostwritten start to finish in the author's speaking voice. • A 60,000-word sweet romance, written to a series bible the author already had. • AI-drafted manuscripts rewritten line by line so they read human and stop tripping detection tools. What I do Book ghostwriting. You bring the story, the expertise, or just an outline. I write the manuscript in your voice. Genres I work in: romance, cozy mystery, thriller, sci-fi and fantasy, Christian fiction, children's books, memoir, biography, self-help, leadership, business, parenting, mental health, and devotionals. Developmental editing. The big-picture pass. Structure, plot, character arcs, pacing, chapter order. You get a written editorial report with specific fixes, not "chapter 4 feels slow" and nothing else. Line editing. Sentence-level work on flow, clarity, dialogue, and tone. Your voice stays yours. Copy editing and proofreading. Grammar, punctuation, consistency, timeline accuracy, style guides (CMOS, APA, MLA, or your publisher's house style). Then one last clean read before you hit publish. AI manuscript humanization. I rewrite AI-assisted text so it reads like a person wrote it. Rhythm, specificity, voice. Not synonym swaps. Amazon KDP formatting. Kindle eBooks, paperback interiors, and print-ready PDFs that upload without errors the first time. How I work I ask a lot of questions up front. I'd rather spend an hour nailing your voice than hand you 20,000 words you don't recognize. Sample chapters early, regular check-ins, and honest feedback when something isn't working. I'll tell you before a reader does. What clients say "Kingsley captures the essence of your thoughts as if reading from your personal diary." "Blown away by Kingsley's work. He delivered a polished, insightful piece that read like it belonged in a best-selling book." What you get Clean manuscript files, Track Changes where it applies, a written editorial report instead of one-line comments, strict confidentiality, full rights to your work, and deadlines I actually hit. Post-delivery support included. Let's talk Message me with your genre, rough word count, and what's bugging you about the project. I'll tell you what I'd do first and whether I'm the right fit. If I'm not, I'll say so.
