A man discovers his own body is the living key to an alien signal — and every three-letter agency on Earth is determined to trigger it... whether he survives or not.

SYNOPSIS:

David Sloan, 50, is the CIA’s most reliable field operative — disciplined, lethal, unbreakable. But since 1987, when a black-op called Project Warden killed his father, an alien virus has lain dormant in his bloodstream. It activates when his heart rate climbs above 140 BPM, turning his body into a living transmitter broadcasting Earth’s location into deep space.

Now the virus is waking.

Three ancient hexagonal modules — scattered across Europe after the fall of the Berlin Wall — are converging again. When they close within 1.6 kilometers of each other, they resonate with David’s infected pulse, amplifying the signal into an interstellar scream. Every ambush, every chase, every near-death moment in his current mission is no coincidence. His own handlers engineered the terror to keep his heart racing and the transmission flowing. They want first contact — on their terms.

David’s only hope of staying human is Agatha Petrov, his ex-wife and former SVR defector. Her presence once calmed the pulse. Years ago, she defected for him; he chose duty. Now she’s back, risking everything to save the man who abandoned her — and the world he might doom.

From rain-slicked Prague to Lisbon’s alleys, Rome’s shadows, Brussels rail yards, and Antwerp’s fog-choked docks, David races to keep the modules apart. But the geometry of Europe has become his cage. Betrayals mount: the briefcase he watched sink is recovered empty, his father’s sacrifice was a lie, and even his closest allies have been counting his heartbeats.

In the final convergence, as the modules lock and the signal peaks, David faces an impossible choice: let the scream go and end humanity’s cosmic loneliness, or find silence in the one person who still sees him as more than a weapon.

One fragile moment of connection could quiet the hum.

But the virus doesn’t die. It migrates deeper. As David and Agatha drive into an uncertain dawn — free from surveillance but never truly alone — something vast across the void begins to turn.

“Eleven minutes.”
