Code of Treason
One man. One mission. One shot at averting war...if he lives long enough.
Adam Knight is on the run. After crippling the same shadow organization time and again, he’s finally pushed them too far—and now a relentless assassin is on his trail.
Meanwhile, a Turkish delegate is gunned down by a Greek operative in Geneva. With two NATO allies on the brink of open conflict, the fragile peace holding the region together threatens to unravel.
Penumbra Division dispatches Knight to investigate the killing and prevent an international catastrophe. From the streets of London to the pristine banks of Switzerland, Knight traces the conspiracy across Europe.
With the help of a determined French journalist chasing her own story, Knight must stay one step ahead of the assassin hunting him while exposing the plot fueling the chaos. Each clue brings him closer to the truth—and closer to his pursuer.
As tensions flare and armies prepare for war, Knight races to prevent a conflict that could consume the world. But in a game where every move is deadly, will he survive long enough to stop it?

My passion for storytelling began as a child, sparked by the exploits of James Bond and the action films of the 80s and 90s. As I grew, I found inspiration in the literary works of Tom Clancy, Michael Crichton, and Lee Child.
In 2024, I released my debut novel, Shadow Operative, the first in the Adam Knight Thriller series. What began as a single book has since grown into a fast-paced, globe-trotting series spanning five novels...and counting.
In June 2025, I launched a spin-off set in the same universe centering on Penumbra Division, starting with The Last Operator.
In early 2025, I signed a multibook deal with Boldwood Books to launch a brand-new series featuring Dane Winter, an elite ex-soldier turned freelance operative. The first book, Hostile Asset, was released in October.
My second Penumbra Division book will be available in Mid-November.
Off the page, I’m a devoted husband and proud father to a son and daughter. Without them, none of this would be possible.
