The Authority Content Mine

Turn your book, talk, or big idea into a month of social content

You have already done the hardest part: creating the message. I transform your existing expertise into polished reels, carousels, Stories, graphics, and social posts that help you stay visible without constantly wondering what to create next.

Five published books Writes fiction as Calla Cross

One source, many pieces

Pick what you already have. Watch it multiply.

This is the whole idea. You hand me one substantial thing you already made. I hand back an organized bank of content built from it.

You send

One book chapter

The pages you already wrote, edited, and published.

One source piece becomes 6 kinds of content. Tap any card.

Counts and formats above are illustrative. Your actual deliverables are set by the package you choose.

The real problem

Your best content may already exist. It is simply buried.

Inside your book chapters, keynote slides, podcast interviews, workshop recordings, and notes are dozens of ideas your audience has never seen.

But turning all of that into social content takes time, design skill, and a fresh eye. That is where I come in.

No blank content calendar required.

Who this is for

Built for people who already have something to say

Authors

You have a published book, a manuscript, or a backlist you are not fully using.

Speakers

You have a keynote, workshop, presentation, podcast interview, or recorded training sitting in a folder.

Experts

You have plenty to say, but you do not want to start from a blank content calendar every single week.

People who want depth

You value thoughtful repurposing of your own ideas more than chasing whatever is trending this week.

What I actually do

Extraction, then design

This is not generic social media management. It is thoughtful content extraction and visual repurposing by someone who understands authorship, storytelling, speaking, and platform-specific design.

  • Identify the strongest teachable, quotable, relatable, and promotional moments in your source material.
  • Repackage those ideas for different platforms and content formats.
  • Create a visually cohesive set of assets that fits your brand.
  • Balance authority-building, value, personality, and promotion.
  • Deliver organized, ready-to-use content instead of a folder full of random graphics.

Charli Cotner, author and content designer for authors and speakers
About Charli

Not a social media theory. Lived author experience.

Charli Cotner is a five-time published author and content creator who also writes fiction under the pen name Calla Cross. Her sixth book releases in September 2026.

She is not approaching authorship as an outsider. She understands the work behind creating a book, the challenge of promoting it long after launch day, and how much valuable content is often left sitting inside the pages.

She has also created Instagram reels, Stories, carousels, TikTok and Facebook content, and professional speaker one-sheets. Her advantage is the combination of real author experience, strong visual design, and practical cross-platform content creation.

Created by a five-time author who understands what it takes to write the book, shape the message, and keep showing up after launch day.

Find her author world on Instagram at @callacrossauthor.

Christmas Confessions, the fifth book written by Charli Cotner under the pen name Calla Cross Book five
The credibility

Five published books — the newest is Christmas Confessions.

Written, published, packaged, and promoted. Charli has done every part of the job she is now doing for you.

The backlist

The four that came before

Every one of these is a full cycle she has lived: draft, edit, cover, launch, and the long promotion after launch day. That is the experience she brings to your content.

Still writing. Still shipping.

Her own work

She does this for herself first

The fastest way to know whether someone can build your content is to look at what they build for their own name. Both accounts are hers.

Questions

Good things to ask before we start

A book chapter, manuscript excerpt, keynote recording, slide deck, podcast interview, blog post, workshop, training video, or another substantial piece of original content.
No. I can work within an existing visual brand or create a simple, cohesive visual direction for the project.
Short captions can be included in the higher package. In lower packages, I can extract post-ready wording or work with copy you provide. Caption writing is also available as an add-on.
Posting and scheduling are optional add-ons. The core service delivers organized, ready-to-use content assets.
No honest content creator can guarantee platform performance. The goal is a more consistent, polished, and strategic presence built from your strongest ideas.
A 50% deposit reserves your project on the calendar. Packages are customized around the amount and complexity of content needed, and final pricing is confirmed before work begins.
Let’s go digging.

You already wrote it. Let’s put it to work.

Send me the chapter, the talk, or the interview. I will send back a month of content built from your own best thinking.
