About Us

Hi, I’m Cassie Armstrong, writing coach, book editor, and owner of MorningStar Editing LLC.

I help authors create clear, engaging, publish-ready books that serve their readers. Whether you’re writing children’s literature, a craft or how-to book, or a cookbook that’s meant to be used and loved, I work with career-focused authors who care deeply about their work and want their books to meet publishing standards.

I’m the editor of two award-winning trade books: Daisy Cakes and South, and I bring a deep respect for audience, structure, and revision to every manuscript I work on.

What matters most to me is helping writers clearly understand their work. I believe great books aren’t just well written—they’re thoughtfully shaped through revision, intention, and a genuine respect for the reader.

That belief applies across genres. A picture book, a craft book, and a cookbook may look very different on the surface, but all successful books share the same foundation: clarity, purpose, and an understanding of who the book is for and how it will be used. My role is to help you strengthen that foundation so your book does exactly what it’s meant to do.

MorningStar Editing LLC exists to provide steady, experienced support for authors who are serious about their craft. When you work with me, you’re not just getting an editor who marks up a manuscript—you’re gaining a coach who helps you see what’s working, what needs refinement, and why those changes matter. My goal is not only to improve your current manuscript, but to help you grow as a writer with skills you can carry into future projects.

I know how vulnerable it can feel to share your work, especially when you want to publish your book. I approach every manuscript with care, honesty, and respect. I offer clear guidance while honoring your voice and goals. Together, we’ll focus on creating a book you can present with confidence—one that’s ready for publishers, readers, and the marketplace.

Let’s talk about your book and how I can help you.

Warmly,
Cassie Armstrong

About Us

Hi! I’m Cassie Armstrong. Thanks for stopping by. I’m the owner and operator of MorningStar Editing. I’m also a word nerd and proud of it. My love of words and good writing goes back to my childhood when I discovered Jules Verne and stayed up all night reading Twenty Thousand Leagues Under the Sea. 

My love of words continued in college where I majored in English and received my bachelor of arts in literature. It expanded in grad school where I majored in English with an emphasis in folklore and received a master of arts in English. I loved exploring how words were used by different cultures in their folktales, jokes, rhymes, songs, riddles, and even cooking. My master’s thesis allowed me to explore a new form of folklore—officelore. I had a blast exploring how offiicelore used visual and written jokes in a new foklore genre.

I’ve been playing with words my entire professional career. First as a teacher with more than twenty years experience teaching students from two years old to eighty-years-young and then as an editor. I may have come to the editing party late and through the back door, but I’m glad I did. I can’t think of anything I’d rather do. Editing gives me the opportunity to do two things I love—working with words and helping authors, and publishers and packagers, achieve their dreams.b

As an editor, I help new authors with their manuscripts while teaching them about the editing and publishing process. I act as their coach, cheerleader, and editor. I’ve helped authors with their children’s books, business books, parenting books, cookbooks, and craft books. I’m as thrilled as the author is when they reach their goal and see their book in print for the first time. I love their enthusiasm and giddiness when they see that all of their hard work paid off. I smile from ear to ear when I see a book that I edited in our local bookstore. And my happiness grows when an author sends me a nice note or asks me to help them with another book. I love my job!

Working with packagers and publishers as an editorial freelancer gives me another thrill. I love it when packagers and publishers contact me to help them with manuscripts that are in different phases of devejoment. I like being contacted and asked to help because of my experience and knowledge in different subjects or genres or because of my experience with manuscript evaluations, copyediting, and proofreading.

Working with packagers and publishers allows me to be part of a tearm and I love that. I’ve helped packagers and publishers with children’s books, cookbooks, and craft books. I’ve also helped with books on parenting, history, fiction, and sports, just to name a few. As with independent authors, I love seeing a book that I edited or proofed on the shelf in my local bookstore.

Do you have a manuscript that needs my help? Contact me and let’s talk about how I can help you.
