What genres do you work with?

My primary focus is Romance and Drama, but I work with all fiction genres — Fantasy, Sci-Fi, Literary Fiction, and more. If your story has characters with emotional lives, I can help.

Do you work in both English and Portuguese?

Yes. I'm fully fluent in both languages and offer all services in English and Portuguese. You can submit your manuscript in either language.

What is the difference between Beta Reading and Narrative Strategy?

Beta Reading is a diagnosis — I tell you what works, what doesn't, and why. Narrative Strategy goes further: I work with you to actively rebuild the elements that aren't functioning, from character arcs to scene structure. Think of Beta Reading as the map and Narrative Strategy as the renovation plan.

How long does it take to receive feedback?

Turnaround times vary depending on manuscript length and current availability. All details and timelines are listed on my Fiverr and Upwork profiles. I always communicate clearly about delivery dates before we begin.

Is my manuscript safe with you?

Absolutely. All services are booked through Fiverr or Upwork, which provide contractual protection for both of us. Your work is never shared, published, or used in any way without your explicit consent.

Helping authors strengthen the stories they already carry.

I read what you wrote. I see what it could become.

picture this:

You spent months on this story. Maybe years.
In your head, it's Oscar worthy. On paper? Not so much…
Your friends read it and say “I liked it!” But… did they really?
Your beta readers say “something feels off here,” but never tell you what. Or why.
That's where I come in.

You wrote the story.

I help it reach its potential.

Here's what I do:

I don't tell you I don't like a character and leave it at that.
I tell you exactly why that character feels flat.
I don't grade your plot.
I study what you were trying to say — and help you find the best way to say it.
I don't rewrite your story for you.
I help you see it more clearly.

This is me!

I'm Damares Santana — founder of Keystone Editorial.

I've always been a reader first. And somewhere along the way, reading became imagining — what if this character did this instead? What if that reveal came two chapters later? I couldn't turn it off.

When I started beta reading for other writers, I held back. It wasn't my story. Who was I to suggest structural changes?

Then I thought: what if that's exactly what they needed?

That question became Keystone Editorial.

I built this for the authors who don't want someone to pat them on the back and send them back in. They want to know — really know — what's working, what isn't, and what their story could become with the right map.

01

Beta Reading

You finished. Now find out if it works.

You wrote the whole thing. Now you need someone to read it — not to be kind, but to be useful.

I go through your manuscript as a reader first, editor second.

I note what's landing, what's losing me, and where the story is doing something different from what I think you intended.

Then I tell you why — with enough specificity that your next revision has actual direction, not just vibes.

Praise where it's earned. Honesty where it's needed.

Narrative Strategy & Character Development

You have the story. Let’s find out what’s missing.

You've already gotten the feedback. It just hasn't helped.

"Something's off." "I don't connect with this character" — but you still don't know what to do about it.

You've written so many drafts that the words have stopped meaning anything.

I read your entire manuscript — plot, characters, emotional arcs, internal and external conflicts, resolution, all of it — and I build you a full, bespoke roadmap of what's already there and how to make it work.

The story you want to tell is already in there. I help you find it.

KU Coffee Read

Published on Kindle Unlimited — but not sure it's working?

You put the book out there. The reviews are trickling in — some good, some vague, some that make you wonder if readers are finishing it at all. But you're not ready to commit to a full manuscript audit just yet.

Fair enough.

Just drop the link to your Kindle Unlimited book. I'll give it a read and share my honest first impressions — what's grabbing me, what's losing me, and whether there are structural patterns worth paying attention to. No templates, no rubrics. Just a reader who knows what she's looking for.

You can buy me a coffee afterwards. ☕
