The Watcher : A Domestic Psychological Thriller of Smart-Home Surveillance, Betrayal, and a Mother's Race to Uncover Who's Listening

Her smart home knows her daughter's nickname. She never told it. Mara Voss built her family's security system herself. She works in cybersecurity — this is what she does. Every camera. Every lock. Every sensor. She knows her network the way she knows her own heartbeat. Then the doorbell greets her seven-year-old by a name only her husband uses. A name that was never entered into any device. A name that has no business being spoken by a machine. When Mara checks the log, the event has been erased. Someone is inside their devices. Not a distant hacker in a server farm — someone close. Someone who knows the private rhythms of her marriage. Someone who has been listening to her bedroom for months. When she reports it, the evidence disappears. When she tells her husband, he looks at her the way you look at a woman coming apart. Mara has one advantage the watcher doesn't know about. She can see the traffic. But the deeper she looks, the more the evidence points somewhere she refuses to go. Not outside. Not to a stranger. Inside her own house. For fans of Freida McFadden and Lisa Jewell — a razor-sharp domestic thriller about surveillance, trust, and the terrifying question of who really knows you best. The devices are always listening. The only question is: who's on the other end?
