Alyssa Matesic – Editor

Passionate book editor who's worked with bestselling authors at Penguin Random House on thrillers, historical fiction, and book club reads.


If you're an aspiring author, I have good news: It IS possible to publish that book you love so much — and feel proud of it. I know how intimidating and downright discouraging the publishing process can feel at times, which is why I offer a unique combination of editorial expertise and industry insight to help you take your story from rough draft to a sparkling diamond in the rough.


I’m a passionate developmental editor dedicated to helping writers feel more confident in their stories and get one step closer to their dream of seeing them published. Between my time at publishing houses, a top-tier literary agency, and editing independently, I’ve worked with 300+ book writers at all stages of their careers — from first-time novelists to New York Times bestselling authors.

With nearly a decade of industry experience, I’ve evaluated and edited hundreds of novels, and I’ve seen what top-notch book publishing looks like at its highest level.

I've held roles at the following:

→ Penguin Random House (Ballantine Books)

→ Macmillan (Henry Holt & Company)

→ The Book Group literary agency

Authors I've worked with are represented by WME, ICM, and Triada, among other literary agencies.


I am a developmental/structural editor — think of me as the first line of defense once you've finished your draft. My feedback will focus on big-picture elements like plotting, pacing, character development, structure, and organization. The goal? Help you tell the best possible version of your story and realize your vision.

My services include:

→ Editorial Assessments
→ Manuscript Makeovers (a comprehensive package including an editorial assessment, a developmental edit, and coaching)
→ Query Reviews (including query letter reviews, synopsis reviews, and sample pages reviews)


It’s critical to ensure the editor you choose has a skillset and background that align with your needs and goals. I truly believe in partnering with writers whose genres and needs sit within my specialties, so I can get you the best possible results.

I offer developmental and structural editing for the following genres:

✓ Thrillers, mystery, and suspense

✓ Contemporary women’s fiction

✓ Historical fiction

✓ Literary fiction

✓ Memoir

✓ Anything that can be devoured in one sitting!

There’s nothing I enjoy more than supporting aspiring authors throughout their book writing journey. When I’m not editing books, you’ll find me sipping an espresso martini, reading about the Titanic, or cuddling my goldendoodle, Luka.

I can't wait to discuss your project!

This was a great experience. Alyssa provided an extremely helpful editorial assessment where she was able to highlight what worked and didn’t work in my manuscript. While positive feedback is always nice, I was most impressed by the level of detail she went into on the areas that needed improvement. Many of these things I was already worried might not be working, others I had just completely be...
