Zone Manirat has always lived in the shadow of his older brothers-Interpol agent Kit and luxury car mogul Kam. But he's carved his own space through adrenaline, speed, and his place on Bangkok's most elite semi-pro racing team. He's got a car he loves, a girl who understands him, and a future that-finally-feels like his.

Then Silo shows up.

Silo, an old family friend and an agent with Thailand's National Intelligence Agency, offers Zone a covert assignment: infiltrate his own racing team and uncover a web of high-tech data trafficking. The twist? Zone's girlfriend Iris is recruited too-and they're not just spying for one agency, but two.

As Zone races to stay ahead of the data thieves, the lines between observation and betrayal begin to blur. Iris has secrets of her own. Silo's still entangled with Kit. And the USB drive Zone received from his dead best friend could be the key to unraveling everything-or destroying what's left.
