When a techno-terrorist group threatens to break encryptions on a global scale, a CIA officer must take matters into his own hands to save a world held hostage.

A massive security breach in China. CIA operations compromised in Turkey. Undercover ops breaking down the world over. A techno-terrorist group dubbed "Archon" has unleashed a terrifying new technology that can break any encryption. Humanity's secrets are about to be laid bare, and global order tilts toward chaos.

Up against a doomsday clock, CIA officer Colt McShane hatches a desperate plan: infiltrate Archon, capture one of the terrorist group's leaders, and force them to divulge the kill switch. But when Colt arrives just in time to see his target assassinated, he realizes that the stakes have been raised. Someone else is killing the terrorists and targeting their technology. And the question is: are they friends, or a new, and even more dangerous, enemy?

Aided by the beautiful and mysterious Ava Klein-an operator in a covert organization known only as Trinity-Colt must stay one step ahead of all who want him dead: international terrorists, government agents, police. Even those he once called friends can no longer be trusted.

Because in a world where power is built on a foundation of secrets, unlimited truth is the most destructive force of all...
