The Alpine Breach — A Cyberweapon Thriller

Six years after walking away from the intelligence world, Nathaniel Cole Winchester boards the Midnight Line, a high-speed luxury train cutting through the Swiss Alps, chasing a single piece of intelligence: a stolen cyberweapon capable of crippling national power grids is somewhere among the passengers. He is not alone for long. Cyber-forensics analyst Isla Monroe traces the courier's digital footprint to a single first-class cabin, only for terrorist strategist Vincent Rourke to seize control of the train's systems, sealing every door and locking two hundred passengers inside a moving prison seven thousand feet above the valley floor.
When demolitions expert Caleb Dorian finds explosive charges wired into the mountain tunnels ahead, the mission changes from recovery to survival. With no signal, no brakes Rourke cannot override, and no way off the tracks, Cole's team has to identify a courier, defuse a countdown they cannot see, and figure out which of their fellow passengers can be trusted before the Alpine night runs out. A locked-room thriller at three hundred kilometers an hour, The Alpine Breach traps its heroes between a hijacker who has already won and a mountain that was never built to be escaped.
