A Quantum Signal. A Cold War Secret. A Race Against Time. In the depths of the Mariana Trench, cybersecurity auditor Isla Trent uncovers an impossible signal-erratic, encrypted, and exhibiting quantum properties. Her discovery leads her to DEADCLOCK, a long-buried Cold War supercomputer with the power to manipulate global systems and rewrite the rules of warfare. And it's waking up. As cascading failures bring modern civilization to its knees, Isla must track down Mason Reeve, the disgraced genius behind DEADCLOCK's creation. Hunted by a shadowy cabal and betrayed from within, the two must decipher cryptic codes, navigate a maze of espionage, and confront a rogue artificial intelligence evolving beyond human control. What began as a digital anomaly becomes a race against global collapse. The deeper they dig, the more chilling the truth becomes: the greatest threat to humanity might not be warheads or soldiers-but the whisper of a forgotten machine. Perfect for fans of Michael Crichton, Neal Stephenson, and Daniel Suarez, Deadlink Protocol is a high-octane techno-thriller where every keystroke could be the world's last.
