A KINGFISHER NOVEL

The Mission Was Controlled. Until The System Looked Back.

A covert operation in Berlin pulls the Kingfisher team into a threat hidden inside the intelligence built to guide them. In Karst Violet, every prediction carries an agenda, every memory demands proof, and the most dangerous command may be the one that sounds like your own voice.

ABOUT THE AUTHOR

Arthur Kenworthy

Arthur Kenworthy writes intelligent thrillers where covert operations collide with emerging technology, institutional power, and the difficult choices that keep people human. His fiction pairs tightly controlled suspense with questions that remain long after the mission ends.

“The most dangerous systems are not the ones that fail, but the ones that work exactly as someone intended.”

THE SYSTEM WAS BUILT TO PREDICT DANGER. NO ONE ASKED WHAT IT WOULD LEARN FROM US

Kingfisher follows an impossible signal from Berlin into a buried intelligence that mirrors choices, preserves what others erase, and turns human uncertainty into a weapon. Enter Karst Violet, where staying alive may require the team to defy the very system keeping them alive.

ABOUT THE BOOK

KARST VIOLET

A ghost asset carrying an impossible signal draws Kingfisher into Berlin—and into a threat no weapon can contain. As PETRA begins reflecting patterns it should not recognize, Chase, Reed, Vega, and Cortez must follow the anomaly across borders before Delta Mirror turns their memories, instincts, and trust against them.

“Kingfisher is not a unit. It’s a containment strategy.”

READER TESTIMONIALS

A Thriller That Stays In Your Head After The Mission Ends

Readers are drawn into Karst Violet for its controlled tension, unsettling intelligence, and characters forced to choose between what the system predicts and what they know is right.

“Karst Violet feels frighteningly possible. The technology is compelling, but the real tension comes from watching Chase and his team fight to preserve trust, consent, and human choice. I kept questioning who, or what, was truly in control.”

Daniel Foster TECHNO-THRILLER READER

“From Berlin’s tunnels to the Caribbean storm line, every setting carries tension. The story moves with precision, but it never loses its emotional weight. This is the kind of thriller that makes you slow down, pay attention, and distrust every easy answer.”

Emily Carter ADVANCE READER

“Smart, atmospheric, and deeply unsettling. PETRA and Delta Mirror are more than pieces of technology; they change how every decision feels. Long after I finished reading, I was still thinking about the line between protection and control.”

Michael Reynolds SUSPENSE FICTION READER
