It’s strike—and counterstrike—as John Dempsey takes the fight to the Russians in a riveting Tier One Thriller by the Wall Street Journal bestselling authors of American Operator.

When shadow warrior and former Tier One Navy SEAL John Dempsey goes undercover to meet with a Vory arms dealer, he thinks he’s laying the groundwork to penetrate the Russian criminal underground. Instead, he walks into a trap orchestrated by Zeta, the secret Russian task force behind a recent assassination attempt on the US President. For Dempsey and his team, the only way out is to lay waste to the Russians, putting a target on Ember’s back.

With Ember pitted against Zeta, a dangerous game of strike and counterstrike ensues—sanctioned in the halls of the Kremlin and the White House but disavowed to the world. As the line between espionage, counterterrorism, and spec ops blurs, Ember is ordered to eliminate their ultimate adversary, which means taking the fight against Zeta to Russian soil. But like a phoenix risen from the Cold War embers, Zeta is more capable than anyone imagines, and the Russians retaliate with an operation that will find Dempsey and task force Ember battling for survival.

An explosive, high-stakes thriller of espionage and counterterrorism by the Wall Street Journal bestselling authors of Tier One.

A shocking attack in Ankara leaves the US Ambassador to Turkey dead and his chief of staff, Amanda Allen, in the hands of brutal terrorists. But Allen is no ordinary diplomat. She’s undercover CIA. The DNI and the President turn to Ember, America’s premier black-ops task force, and its deadliest weapon, former Tier One Navy SEAL John Dempsey, for help. To find Allen, Ember gets embedded in the most dangerous battlefield on Earth: Syria. But when all communications are disabled by an attack in Turkey, Dempsey finds himself with no backup—a lone shadow warrior racing against time to rescue Allen from her captors before she reaches her breaking point.

What Dempsey doesn’t realize is that Allen is just a pawn in a much larger game. A new player has already been unleashed: a legendary mercenary who matches the American Operator in skill, tactical prowess, and a killer instinct for survival. Now there is far more at stake than a kidnapped CIA agent. Dempsey and his team better get this one right, because the balance of power for the entire Middle East rests on their shoulders. And the new threat is far more dangerous than any Dempsey has encountered in his decades waging war against terrorism. Game on.

A Wall Street Journal bestseller.

John Dempsey, former Navy SEAL and Tier One operator, is back. Only a few months into his new life as an operative for Ember, the United States’ most covert counterterrorism entity, he must stop an old nemesis who’s resurfaced after ten years of operating in the shadows. From the deserts of Iraq, through the jungles of Guatemala, to the streets of suburbia, Dempsey and his Ember team race against time to stop a series of horrific and devious attacks against the homeland.

In this second installment of the Tier One series, John Dempsey faces his greatest challenge as he continues to evolve from a decorated Navy SEAL into the country’s most lethal protector.

Nothing stops former Navy SEAL and Tier One operator John Dempsey from answering the call of duty—including a mission with the highest stakes he’s ever faced. When one of the most brazen and lethal acts of terrorism rocks American and Israeli intelligence forces at the highest levels, Dempsey’s ultracovert antiterror unit, Ember, mobilizes.

But this operation isn’t just a retaliatory strike by Ember; it’s a mission of vengeance for Dempsey—against the Iranian terrorist mastermind who slaughtered Dempsey’s Tier One comrades. Racing from Tel Aviv to Tehran, the elite American warrior and his formidable Israeli counterpart must forsake their backup in a capture-or-kill gambit that could turn into a suicide run.

But with missiles flying across the Middle East, Dempsey’s do-or-die quest must succeed. If it doesn’t, it’s a short countdown to World War III.

In a world violated by terror, the old lines have blurred. Meet the next generation of covert ops.

John Dempsey’s life—as an elite Tier One Navy SEAL named Jack Kemper—is over. A devastating terrorist action catapults him from a world of moral certainty and decisive orders into the shadowy realm of espionage, where ambiguity is the only rule. His new mission: hunt down those responsible for the greatest tragedy in the history of the US Special Ops and bring them to justice.

But how does a man torn between duty and revenge walk the line and preserve his soul?

As Dempsey struggles with the games of spies, the case propels him across the globe in a desperate effort to prevent a new, horrifying attack on American soil.

Once, John Dempsey followed orders blindly. Now he sees behind the curtain, and the security of the civilized world rests on one question: Can a Tier One Navy SEAL adapt and become the world’s most lethal spy?
