He was the help. She was the heiress. Now, he's the only one who can keep her alive.

Vespera Thorne is the acting Chairperson of Thorne-Aviation, a multi-billion-dollar empire built on her father's legacy and a mountain of secrets. But when she discovers "Project Icarus"?a digital backdoor embedded in global defense systems?she realizes her family's greatest achievement is actually a countdown to catastrophe. With her board of directors compromised and her uncle, Silas, tightening the noose, Vespera is a woman with a target on her back and nowhere to run.

Renwick Koda left the Thorne Estate twelve years ago in handcuffs, framed for a crime he didn't commit by the very family his mother served. Now a elite Strategic Auditor, Ren specializes in dissecting corporate rot and extracting high-value targets from the shadows. He has every reason to hate the Thornes, and even more reason to let Vespera face the music alone.

But when a lethal extraction team breaches the Thorne penthouse, Ren is the only one who breaks through the glass to save her.

Forced into a high-octane game of cat-and-mouse across the city's underbelly, the two must bridge a decade of resentment. As the "Vane Debt"?a secret history of stolen intellectual property and blood money?comes to light, Ren and Vespera realize their childhood bond was the only thing that was ever real. To stop Silas and a shadow organization from weaponizing the sky, Vespera must be willing to burn her family name to the ground, while Ren must decide if protecting the woman he was programmed to hate is worth losing the career he fought to build.

In a world where loyalty is a luxury and the truth is a death sentence, their most dangerous match is each other.
