Zero Hour

72 hours ago, a Russian nuclear submarine went dark. 24 hours ago, its weapons officer defected. Right now, a billionaire is buying his way to the end of the world.

When ex-SBS operative Stirling Hunt executes a retired Russian admiral in a Sicilian hotel, he expects a clean kill. The flash drive in the dead man's pocket says otherwise.

Stolen nuclear warheads. An Arctic launch site buried beneath Greenland's ice. And an ideological billionaire who has decided the world needs to be reset.

With ex-Delta assassins hunting him and his own handler trying to burn him before he reaches London, Hunt races from the Mediterranean to the edge of the world. MI6 wants deniability. Wall Street wants profit. And someone in Downing Street wants Hunt dead before he can connect the dots.

When the countdown reaches zero, there are no second chances.

Zero Hour is the explosive finale to the four-book Stirling Hunt series—globe-trotting espionage thrillers from veteran Stewart Clyde, for readers of Daniel Silva, Mark Greaney, Brad Taylor, and Jack Carr.
