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!

I had the pleasure of recently collaborating with Alyssa on the submission materials for my latest horror novel and all I can say is that she is extremely knowledge about the industry. Her assistance really helped me hone in on what agents are looking for. I've struggled in the past trying to write a decent query letter and craft a synopsis that isn't confusing and her assistance on those defin...

Alyssa is a treasure trove. She cost more... because she is worth more. It was truly a learning experience working with her, and I look forward to collaborating with her in the future (when I get around to fixing all the things she pointed out to me in her assessment - LOL). She was thorough and professional throughout, delivering a meaningful assessment on the exact date that she quoted. With ...

Alyssa delivered everything she promised - and MORE! I got (1) things that were working, (2) things that needed to work, and (3) things that needed clarifying. I would expect this from any reputable editor, but where Alyssa went way beyond expectations was in giving me very concrete, detailed, and thoughtful notes with specific suggestions for how to strengthen my manuscript. If YOU have the o...

Now, for my third book, I couldn't have been more excited for her to do a developmental edit. Alyssa has provided detailed feedback on how to strengthen the plot, and how to develop certain characters more-- essentially making my manuscript stronger. ...

So much more than I expected, so much more! I expected professionalism. I got compassion, encouragement, and detailed, insightful feedback. I've published two books, including with a top 2 book publisher in the world, and I've worked professionally as a writer. Alyssa is the best I've ever worked with. And I don't leave reviews like this ... ever.
