SUBSONIC
They Weaponized a Sound No One Can HearBy Cole Ashford
Length1h 3m
About this audiobook
Some frequencies are too low to hear. That's what makes them perfect for killing.
Disgraced FBI audio analyst Elias Thorne lives with a constant ring in his ears—the souvenir from the raid that killed his partner. So when an anonymous message drops a single sound file into his inbox, he's the last man who should press play.
He does anyway.
The frequency is already humming through Chicago's power grid and into its water. In six hours it hits full strength: mass cardiac arrest, 80,000 dead. And Elias is the only one who can hear it—the only one who can trace it to the source and shut it down.
The hunt drags him beneath the city, after a weapon built by a dead man and perfected by people who never existed. To survive it, he'll trust a woman he shouldn't and bargain with the one man he swore he'd never work with again.
But stopping the frequency was never the point. Someone built this night to see if he could.
And they're still listening.
