Burnout
When tech genius Nathan Wiley is ambushed outside his London home, Group Fifteen operative Charlie Cooper is pulled back into the shadows. The attack was no random mugging—Wiley’s name was leaked by a whistleblower with access to one of the most sensitive intelligence troves in Five Eyes history.
The source? Sienna Jones, a former Australian spy who vanished without a trace after exposing the West’s illegal use of AI trained on its own citizens. But now a signal has emerged from a luxury wellness resort on a remote Greek island. Jones might be hiding there—or someone wants the world to think she is.
Undercover and outnumbered, Cooper enters a world where nothing is as it seems. Staff members are lying. Surveillance is everywhere. And when a deadly ambush leaves Cooper fighting for his life, the mission becomes clear: locate Sienna Jones, secure the stolen intelligence, and survive long enough to discover who else is playing this deadly game.
Because someone wants the truth buried—along with everyone who tries to expose it.
