Price of Duty (Patrick McLanahan #21) by Dale Brown

The U.S. and its Western allies come under a diabolical Russian cyber warfare attack in this action-packed military techno-thriller from New York Times bestselling master Dale Brown.

In a top-secret location deep in the Ural Mountains, Russian President Gennadiy Gryzlov has built his nation’s most dangerous weapon since the atomic bomb—a fearsome tool to gain superiority in Russia’s long-running battle with the West.

From inside Perun Aerie—an intricate network of underground tunnels and chambers that is the heart of the Russian cyber warfare program—he is launching a carefully plotted series of attacks on an unsuspecting U.S. and its European allies.

With the world’s fate hanging in the balance, will Scion succeed in turning back Gryzlov before he can realize his terrifying ambition to conquer the globe? And what will the toll of victory be?
