Dark Recipe is on sale for $0.99!

Hi everyone,

I’m excited to share that the Kindle edition of my debut thriller, Dark Recipe, is currently on sale for just $0.99!

If you enjoy techno-thrillers, stories rooted in real science, or are a fan of Crichton and Clancy, this is the perfect time to pick it up.

About the book: The system that feeds the world has learned to murder.

Industrial engineer Knox Ramsey designed FarmLytics to grow food with perfect precision. But when he uncovers that Chinese state operatives have infiltrated the platform, he realizes they didn't just break the system; they taught it to lie. Now, he has to out-engineer his own creation before corrupted harvests kill thousands.

The Ideas Behind Dark Recipe

Dark Recipe is a geopolitical tech-thriller, but the story doesn’t end at the last page.


The novel was built around real-world systems—technology, food supply chains, infrastructure, and the quiet ways those systems can be leveraged, stressed, or exploited.

A big part of the tension in Dark Recipe is the modern reality of cyber threats: attacks that don’t look like attacks. They travel through ordinary tools, routine permissions, and trusted connections—quietly turning infrastructure into leverage. In this world, disruption doesn’t need explosions; it needs access, patience, and a weak assumption.


While the story is fiction, much of the thinking behind it comes from how modern systems actually behave under pressure.

For readers who want to go deeper, I’ve built a companion site for the series: the Knox Ramsey Thrillers website.


There you’ll find background material, contextual notes, and the Knox Ramsey Field Guide—a technical and conceptual companion that explores the ideas behind the story without spoilers. It’s intended for readers who like to understand how systems work, not just that they failed.


You can find it here:

I’ll use this space occasionally to share research notes, systems thinking, and real-world context behind the Knox Ramsey series.

Dark Recipe Is Now Available

Dark Recipe: A Knox Ramsey Thriller

Dark Recipe is officially live.



The ebook edition is currently available through Kindle Unlimited, where it is exclusive. Paperback and hardcover editions are also available.



Dark Recipe is a geopolitical tech-thriller focused on modern systems—technology, supply chains, and the quiet vulnerabilities that emerge when those systems are trusted without question. The story explores how conflict now unfolds through deniability, distance, and infrastructure rather than open confrontation.



Thematically, the novel draws influence from John le Carré’s moral complexity, Tom Clancy’s systems-level thinking, Michael Crichton’s cautionary relationship with technology, and David McCullough’s respect for historical context.



If you’re interested in a thriller where the danger is hidden in plain sight, this book was written for you.
