When your safe haven becomes your prison, and the technology you trust becomes the weapon, survival means facing the predator who knows your every vulnerability.Kira Chen has spent three years engineering the perfect sanctuary. As a late-diagnosed autistic cybersecurity specialist, she's transformed her smart home into a precisely calibrated refuge from sensory overload-blackout curtains, temperature-controlled comfort, and white noise machines that silence the chaos of the outside world. But when her apartment's smart systems turn against her in the middle of the night, strobing lights and deafening frequencies push her into complete meltdown. What begins as a technical malfunction reveals itself as something far more sinister: a serial predator who weaponizes technology against autistic women, studying their sensory profiles to deliver torture so precise it leaves no physical evidence. Police dismiss her claims. Friends question her perception of reality. And every night, the attacks intensify, timed perfectly to her sleep cycles, exploiting her neurology with terrifying accuracy. For this psychological thriller with a twist, the hunter has chosen the wrong prey.Teaming up with Morgan, a survivor who escaped the same digital nightmare, Kira uncovers a chilling pattern of disappearances and deaths ruled accidental-all autistic women living alone in smart apartments, all targeted through the very accommodations that should have kept them safe. This domestic suspense escalates into a high-stakes cat-and-mouse game as Kira transforms from victim to investigator, infiltrating the smart home company to expose the monster hiding in plain sight. The techno-thriller elements collide with disability representation rarely seen in crime fiction, creating a nerve-shredding race against time where sensory sensitivities become both vulnerability and superpower. As the body count rises and the killer realizes Kira is hunting him back, she must make an impossible choice: flee like the others, or turn her apartment into a trap and face a predator who's been watching her through her own cameras for months.In this pulse-pounding suspense novel that readers call "a masterclass in tension" ★★★★★ and "the most terrifying thriller I've read because it feels so real" ★★★★★, the question isn't just who's behind the attacks-it's whether Kira can survive long enough to stop him before he claims his next victim.
