From #1 New York Times bestselling author Brad Thor and USA TODAY bestselling author Ward Larsen, comes a heart-pounding thriller of survival, espionage, and global brinkmanship, where the frozen Arctic becomes the deadliest battlefield on Earth.

A vanished plane. An earth-shattering secret. A countdown to World War III.

Hemisphere Airlines Flight 777—the most advanced jetliner ever built—disappears without a trace over the North Pole. Crippled by sabotage, it crash-lands on the ice, stranding the surviving passengers in a wasteland of frigid cold and chaos.

The real storm, however, is still coming.

Hidden inside the wreckage is the prototype for a revolutionary piece of technology that could upend the balance of world power. Now Washington, Moscow, and Beijing are racing to be the first on scene to retrieve it—at any cost.

Trapped in the middle of the world’s most dangerous flashpoint are CIA operative Kasey Sheridan and former fighter pilot turned first officer, Brett Sharpe. Hunted by enemy forces, they must spirit both the device and its creator across the ice to safety—before rival superpowers turn the Arctic into a war zone.

With the clock ticking and the temperature dropping, the fate of the free world is about to be decided at the top of the globe.

"Like a combination of THE HUNT FOR THE RED OCTOBER, ICE STATION ZEBRA, and Jack London’s TO BUILD A FIRE" * The Regan Revolution *
