About "Eyes of the Sentinel"

Sentinel was built to keep people safe. It may be doing far more than that.

Cera Gatch helped turn Sentinel from a struggling startup into a nationwide phenomenon—an app where everyday citizens use drones, live feeds, and collective vigilance to help law enforcement track criminals in real time. Millions watch. Millions subscribe. Justice has never been so visible.

But when suspects who evade conviction begin dying under suspicious circumstances, Cera notices a pattern no one else wants to see. Each death fuels outrage, clicks, and explosive growth. Each one is quietly celebrated by users hungry for retribution.

As Cera digs deeper, she uncovers evidence suggesting Sentinel isn’t just exposing criminals—it may be enabling their execution. With powerful investors closing in and the charismatic CEO she once trusted determined to protect the brand at any cost, Cera becomes a liability.

Watched by the same system she helped build, Cera must decide how far she’s willing to go to stop a platform that’s turning public justice into entertainment—and whether truth can survive in a world where everyone is always watching.

Eyes of the Sentinel is a gripping techno-thriller about surveillance, morality, and the terrifying ease with which good intentions can become weapons.
