ThrillerFest 

You're at ThrillerFest. And you just found the next medical thriller that's going to keep you up past midnight.

When an algorithm decides who gets the ambulance, one paramedic becomes the only variable it cannot predict. ~100,000-word medical thriller. In Final Draft.

You found the signal.

The algorithm knows your name, your insurance status, your age, your zip code, and your medical history . And, in two hundredths of a second, it’ll decide whether you're worth the fuel it takes to send an ambulance.

Or not.

Read Chapter One
What's your Patient Value Index?

This isn't just a thriller. It's a blunt-force reckoning with a system where formulas outrank humanity and every page leaves a bruise.

If you've stayed up past midnight with Michael Crichton, Blake Crouch, Harlan Coben or Andy Weir, I wrote this book for you.

Editors, Agents, and Publishers

Seeking representation. Let's talk.

  • The AI healthcare space is moving faster than the news cycle.

    Based on 2024 reports, major U.S. cities and counties implementing AI-powered 911 dispatch triage to manage call volumes and non-critical cases include Phoenix (Arizona), Fort Myers (Florida), and Jefferson County (Colorado).

    Insurance claim-denial is currently under Congressional scrutiny. Meanwhile, the medical thriller shelf has been dominated by hospital procedurals -no one has written the EMS story, from the street level, with this level of operational accuracy. The Devil's Ledger is positioned perfectly at the intersection of timely and underserved.

    • GENRE: Medical / Tech Thriller.
      WORD COUNT : ~100,000 words.
      TONE: Grounded, tense, and relentlessly procedural.
      COMP TITLES: Readers of Michael Crichton, Jack Carr, Blake Crouch, David Baldacci, Harlan Coben, and Andy Weir.
      STATUS : Manuscript in Final Draft · ARC program active.
      SETTING : Contemporary Denver — EMS / emergency dispatch / AI systems.
      SERIES : Planned trilogy; Book 1 standalone.

  • I spent more than a decade on the streets of Denver as a First Responder -from rookie EMT to Paramedic field training officer. I worked mass-casualty incidents, officer-down calls, and pediatric cardiac arrests. I was the person to the left of the gurney when the system worked. And when it didn't.

    I didn't start writing The Devil's Ledger to make a point. I started because the systems I'm describing in this book are already in place -and most people don't know it yet.

  • Algorithmic healthcare is not a speculative premise. As AI becomes more widespread, health insurance companies are already using it to triage claims. And dispatch optimization software is already live in multiple U.S. cities.

    The Devil's Ledger is the first thriller built from the inside of this system, written by someone who worked it for over a decade.
