A blizzard buries the Colorado Rockies. Six hundred meters below the snow, the world's communication lifelines are under attack.

When a ghost from the past seizes control of the Global Orbit Command Nexus, systems engineer and former cage fighter Ronan Vex finds himself the last line of defence. Hunted through sealed corridors, battling armed operatives and a ticking countdown, Ronan must fight harder than he ever did in the ring - not for a title, but for every voice on earth.

Blackout Protocol is a pulse-pounding action thriller of endurance, sacrifice, and one man's refusal to go silent.
