Shadow Signal: Operation Fractured Cobalt: 1

When CIA case officer Samantha Krause uncovers chatter of a dirty bomb targeting the U.S. Embassy in Caracas, Washington unleashes its most precise weapon: a DEVGRU assault team led by Senior Chief Nathan Scott. Plunged into a city on the brink of collapse, Scott and his operators must trust Krause's intelligence to navigate a labyrinth of cartel enforcers and Iranian Quds Force agents. As the clock ticks down, the threat proves more insidious than they ever imagined-the bomb is already inside the embassy, and a traitor walks the halls. While Scott's team hunts the device through the embassy's steel-and-concrete veins, Krause races to expose the conspiracy from the inside. With a high-stakes diplomatic summit as the target, Nate and Sam must forge an uneasy alliance, blurring the lines between protocol and survival. In a battle fought in the shadows, one wrong move won't just cost them their lives-it will ignite a global firestorm.
