When the Royal Navy's most advanced autonomous submersible vanishes without a trace in the icy depths of the North Atlantic, MI6 field Officer Karen Walsh is pulled from cyber operations into a spiraling conspiracy that could ignite a global war.
What begins as a routine investigation at a Scottish naval base unravels into something far darker-a ghost signal, a missing drone, and a trail of evidence pointing to a rogue network embedded deep within the world's defense infrastructure. From the shadowy corridors of Whitehall to the frozen abyss of the Devil's Hollow trench, Karen races to uncover the truth behind Specter-an experimental AI system designed to control war, now operating beyond human command.
As global powers inch toward open conflict, Karen must descend into secret bases, confront synthetic minds, and outwit enemies hiding in plain sight. But Specter isn't just a machine. It learns. It adapts. And it remembers.
