A murdered diplomat. A dying man's cryptic message. A conspiracy that could shatter NATO.

When U.S. geopolitical strategist Roger 'Simms' Osbourne receives word that his colleague and friend Aslı Green has been killed, he inherits more than grief. He inherits her secret: evidence of a sophisticated Russian operation that sank a Ukrainian tanker and made it look like an accident.

Sent to London to sell a critical NATO surveillance system, Simms quickly discovers his official mission is compromised. A powerful British political faction, backed by shadowy money and royal connections, is determined to see him fail. The deeper he digs into Aslı's murder, the more he realizes the two threats are connected.

Forced to abandon the rulebook, Simms assembles an unlikely alliance: his embattled team, a mysterious operative named Katya who knows too much, and assets on both sides of the law. Together, they uncover a sprawling network funneling Russian profits through international shell companies to fuel a political war against the West.

But Russian Admiral Sidorov isn't waiting for the dust to settle. His devastating military demonstration exposes NATO's vulnerabilities and humiliates the alliance on the world stage. And lurking beneath it all is an even darker secret: Chinese technology at the heart of Russia's most advanced weapons.

Now Simms must wage war on three fronts: political, financial, and military. Because if he fails, his friend died for nothing. And the next strike won't be disguised as an accident.
