The Final Mercy

In the wake of a high-stakes international arbitration case between automakers, a prominent executive is destroyed by an online witch-hunt and leaps to his death. Years later, his daughter, a reclusive cybersecurity architect, deploys a clandestine data-scraping system to identify every single person who posted malicious comments. One by one, she stages elaborate "accidents" to punish them, believing that true justice exists only beyond the law. As federal agent Lena Voss closes in, the hunter becomes a mirror reflecting a society's darkest digital sins.
