A retired MI6 deputy director opens his door to a journalist who isn’t a journalist. She shakes his hand. Three days later he’s dead. The pharmaceutical compound that stopped his heart was delivered through the handshake — and the woman who killed him spent nine months in a Damascus prison cell because he signed the paper that put her there.

Someone is executing intelligence officials across five countries. Not randomly — methodically, scored by a weighted system that measures guilt like a financial audit. The targets all share one thing: they authorized their agencies’ participation in a marketplace that sold behavioral prediction tools to governments, then severed the careers of the officers who knew too much. The abandoned officers found each other. They found a leader. And now they’re working through a list.

Jack Mercer — former Force Recon captain and covert intelligence operative — deploys his family across three continents to prevent the next kill while hunting the man behind the campaign. Elena Markham wages the espionage war from the compound’s oak table, cracking servers across three countries in a single coordinated assault. Hawk Hawkins leads a special forces team into a Portuguese farmhouse to capture a man who reports to seven photographs on his wall every morning. And a dead cartel lord’s son walks into the enemy’s compound wearing a belt buckle that transmits everything he sees.

But the conspiracy has a second layer: a U.S. cabinet member is using the assassination campaign as cover to bury evidence of his own complicity. The military thriller’s most dangerous enemy isn’t the killer — it’s the institution protecting itself.

The chain is severed. The international action is relentless. And the family that survives this war will never go home again — because home no longer exists.
