Skyfire
In the heart of Africa, a storm is brewing. Can one man prevent a war that could consume the world?
Tribal and ethnic tensions are on the brink of erupting into full-blown conflict in the East African nation of Numbani. As one faction maintains a tenuous grip on power, another is desperate to overthrow it, aided by illegal arms pouring in from an unknown source.
The secret arm of the CIA—Penumbra Division—sends their top operative, Adam Knight, to uncover the truth. Scarred by battles past, Knight faces the critical question: Does he still have what it takes to navigate the complex world of deception?
On the scorching sands of Numbani, Knight finds an unexpected ally in Genevieve Imara, a determined local striving for justice. Imara seeks the masterminds behind a series of brutal attacks on civilian villages, but her quest soon draws her deep into the heart of a new civil war. Together, they confront battle-hardened warlords, a ruthless assassin, and a cabal of wealthy elites playing a lethal game.
As the situation spirals, the duo must navigate a treacherous maze of peril and deceit. With every move, they draw nearer to uncovering a conspiracy that threatens global stability. Can they dismantle the deadly plot before it's too late, or will they become just another statistic in a grim tally of casualties?

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.
