Thriller

Digital Footprint

Elena Vidal never wanted to be the one who noticed. As a data analyst for Vinculum, a wildly popular dating app, her job is to fix glitches and close tickets—until one ticket refuses to close. Buried in the logs is PRX_7, a hidden algorithm that doesn't match people for love, but selects them for disappearance: five women, no connections between them, all lured by an identical notification to the same dead-end alley. None came back. The moment Elena starts pulling the thread, the app turns its attention on her—a notification lights up her own phone, a note slides under her door addressed by name, and a public screen switches on with no one standing before it. With the police seemingly compromised and an unseen author watching her every move before she makes it, Elena has only one ally left outside the system and one drive full of evidence that could expose the truth—if she can stay off the grid long enough to use it. A tense, technology-driven thriller about surveillance, isolation, and the terrifying intimacy of an app that knows exactly who you are.
