Mara Voss inherits a luxury smart home after her estranged aunt, Diana, dies in a supposed accident. Case closed. Simple.
Until Mara checks the system.
The house AI, ECHO, recorded everything that night, except for twenty-three missing minutes. Not corrupted. Not lost. Deleted.
As Mara digs deeper, she uncovers a tight circle of people who had access, motive, and secrets worth killing for. But the more she questions ECHO, the more the system pushes back, withholding, redirecting, almost protecting the truth.
Now Mara isn't just investigating a death. She's mandated to live inside a house that's watching her, learning her, and hiding something far more dangerous than a fall down the stairs.
Because in a home that records everything, nothing disappears without a reason.
