Sovereign Ghost

When a mysterious transmission mimicking a Soviet nuclear launch command is intercepted in Arctic Norway, global tensions flare to levels unseen since the Cold War. The terrifying reactivation of RED WINTER-a forgotten dead man's switch capable of triggering a nuclear chain reaction-forces the CIA to send in its most capable ghost: John Nash, a black ops specialist with a reputation for doing what others can't...
or won't. Pulled from the shadows of Berlin and paired with Katya Sokolova, a brilliant former GRU analyst now in exile, Nash is tasked with tracking the origin of the signal to Station Valkov, a long-abandoned Soviet facility buried beneath glacial ice. But what begins as a covert infiltration spirals into a desperate race against time as they uncover an ultranationalist plot to restore a fractured empire-by plunging the world into nuclear chaos.
As Nash and Katya battle elite mercenaries, rogue drones, and treacherous terrain in the Arctic's deadly embrace, they uncover chilling secrets frozen in time-Soviet submarines still waiting for launch codes, surveillance AI fused with Cold War hardware, and Nash's presumed-dead teammate, Dmitri Volkov, now working for the enemy. Torn between duty, loyalty, and personal vengeance, Nash must stop General Karpov, the architect of RED WINTER, before the signal is transmitted and war becomes inevitable.
Featuring explosive combat, psychological intrigue, and a haunting atmosphere of isolation and paranoia, Sovereign Ghost is a cinematic, high-stakes thriller where every step forward cracks the ice beneath your feet-and every choice could spark global annihilation.
