Zero Day Heart
sindo hane
Calyx Thorne is a cyber defense mogul and the CEO of Aegis Security, a company trusted by governments and global corporations alike. Controlled, brilliant, and emotionally sealed, she’s built her life on encrypted walls—until someone breaches them with surgical precision.
The breach isn’t just professional. It’s personal.
The ghost behind the attack is Orson Reed, known in the hacker underground as “Nyx.” He’s Calyx’s ex-lover, the one who vanished five years ago after shattering her heart and disappearing into digital oblivion. Now he’s back—with secrets, with a plan, and with enemies who won’t hesitate to kill them both.
As they’re forced into an uneasy alliance to expose a weapons-smuggling empire embedded deep within the global tech elite, sparks reignite. But trust, once broken, is the most dangerous vulnerability of all.
Set in rain-slick cities, glowing with neon and betrayal, Zero Day Heart is a high-stakes romantic techno-thriller that explores love, loss, and the fine line between firewalls and feelings.
