Six months after stopping a traitorous plot at the heart of the British government, MI6 agent Jac Fenwick and his new deniable-ops unit, 'Rebirth', are plunged into a deadlier, more insidious war. The suspicious death of a GCHQ analyst uncovers a chilling secret: a Russian sleeper program, codenamed the Atlantis Protocol, embedded in the physical infrastructure of the global internet. This is no mere backdoor; it's a revolutionary weapon that can rewrite reality itself, altering financial markets, military commands, and political truths in real-time.

Hunted by a new generation of ruthless SVR assassins and betrayed by a mole deep within their own intelligence community, Fenwick and his partner, Anya Sharma, must go dark. Their mission takes them from the clandestine poker rooms of Geneva to a final, brutal confrontation at a remote cable landing station in the desolate ice fields of the Arctic Circle. Here, they must battle not only elite Spetsnaz soldiers but also the architect of the protocol, a shadowy Russian colonel who is a master of the new, silent warfare.

In a desperate, two-front war against both physical and digital enemies, Fenwick and Anya must risk everything to prevent a global financial collapse and a new world order dictated from Moscow. "The Atlantis Protocol" is a race against time where the battlefield is the truth itself, and the price of victory is the horrifying realization that in the 21st-century cold war, the most dangerous weapon is the one you can't see.
