Clear, confident, publish-ready manuscripts—for authors who take their work seriously.

Editing and coaching for children’s books, cookbooks, and craft books

I’m Cassie Armstrong, owner of MorningStar Editing LLC. I combine professional editing with the heart of a teacher and the insight of a coach—so you don’t just get corrections, you gain clarity, direction, and confidence in your work.

I help children’s authors and nonfiction creators turn promising drafts into clear, engaging, publish-ready books. I work with career-focused authors who want their books to truly serve their readers and stand out in today’s competitive marketplace.

As the editor of two award-winning trade books, I bring a deep respect for audience, structure, and revision to every project. Together, we’ll strengthen what’s already working, address what’s holding the manuscript back, and shape a book you can be proud to publish.

Let’s talk about your book—and what it needs to be clear, confident, and ready for publishing.

About Us

Hi, I’m Cassie Armstrong—writing coach, book editor, and owner of MorningStar Editing LLC. I help writers clearly understand their work and shape books with intention, clarity, and respect for the reader.

I work with authors to create clear, engaging, publish-ready books that truly serve their audience. From children’s literature to craft and how-to books to cookbooks meant to be used and loved, I partner with career-focused writers who care deeply about their work and want their books to stand out in today’s marketplace.

I’ve had the privilege of editing two award-winning trade books, Daisy Cakes and South, and I bring those lessons to every manuscript I work on. My focus is helping you see what’s working, what could be stronger, and—just as importantly—why those changes matter, so your book does exactly what it’s meant to do.

Books aren’t finished simply because they’ve been revised; they’re finished when they clearly communicate with the right audience. I approach every manuscript with care, honesty, and respect, honoring your voice while guiding you toward a book you can share with confidence….
