Radiant Sentry

An Expionage Techno-Thriller

MAJOR WILL MORGAN is a 15-year veteran of the U.S. Army Counterintelligence Command (ACIC) at Fort Meade. A legendary figure in military intelligence, Will leads the Army’s most elite CI team — an unyielding taskmaster with a sharp mind and a loyal heart. His life is the mission.

As the global race for space supremacy escalates, the U.S. stands at a crossroads. Rivals like Russia and China are pouring resources into militarizing space. Russia’s latest threat: a nuclear-powered, space-based anti-satellite system capable of disabling America’s satellites via electromagnetic pulses —jeopardizing everything from missile defense to communications.

DARPA, “the Pentagon’s brain,” has quietly launched a Space Superiority Initiative to counter the threat. But when the CIA’s deep – cover mole in Moscow transmits a classified DARPA document suggesting a Russian mole embedded within a top defense subcontractor, panic ensues.

The Pentagon assigns Will and his team to lead the most critical counterintelligence investigation of their careers. The mole must be found—and fast. The order is clear: No limit on resources. No margin for error.

As Will assembles his team, including DEREK WILSHIRE, an Asperger’s-diagnosed mathematical savant with a genius for patterns and encryption, the CIA intercepts a second Russian document. This one suggests the space system may already be compromised. Derek confirms the worst: the mole has access to DARPA’s most sensitive files.

The investigation quickly narrows to three lead physicists — all brilliant, all deeply embedded. The pressure intensifies as the team races to expose the traitor. But the truth is even more dangerous: the mole is a double agent, protected by the FBI.

Just as the net tightens, U.S. Space Command confirms the unthinkable—a Russian killer satellite has destroyed one of America’s retired satellites in orbit. The system works. The U.S. declares a Dark Sky alert. Space is now an active warzone.

In a last-ditch effort to slow Russia and buy DARPA time to respond, Will’s team launches a bold countermeasure: using the FBI double agent to feed disinformation back to the Russians, sending their program into disarray. The move buys precious time as DARPA races to deploy a leapfrog defense.

But the cost is high, and the clock is ticking.

“Authentic, intelligent, and gripping — Radiant Sentry delivers the realism of Le Carré with the pulse of Clancy. A modern espionage thriller that feels shockingly real.”

“Finally, a spy thriller where the women aren’t sidekicks — they’re the brilliance driving the mission. Sharp, high-tech, and deeply human.”

“A high-tech espionage thriller with brains, heart, and authenticity. One of the best in years.”

“Feels like living inside a real counterintelligence operation — tense, smart, and impossibly hard to put down.”

This is the first book in the Watchtower Series, introducing Team Watchtower—an elite investigative unit within the U.S. Army Counterintelligence Command (ACIC).

Most espionage thrillers revolve around the CIA. However, following the National Defense Authorization Act (NDAA) of 2025, ACIC was formally elevated from a primarily intelligence-focused agency into a hybrid counterintelligence and law enforcement command. This landmark change granted its civilian special agents limited federal arrest authority for national security crimes and expanded its operational scope beyond military installations.

Today, ACIC stands as the only counterintelligence organization with both foreign and domestic jurisdiction—and the legal authority to investigate, detain, and prosecute espionage within and beyond U.S. borders.
