The Silence Frequency

Neuroscientist Dr. Kira Voss thought she was mapping the boundaries of human consciousness. Instead, she found the off switch. During a routine experiment at the Zanetti Institute, Kira discovers a frequency modulation that temporarily silences the conscious mind without shutting down the brain. The subject goes blank - eyes open, breathing steady, but nobody home. It is the most dangerous discovery in the history of neuroscience, and within days, a military contractor named Aethelred Dynamics comes knocking.
General Marcus Thorne (ret.) sees Project Stillness as the future of warfare: a non-lethal weapon that can neutralize an enemy without a single casualty. But the first human test goes catastrophically wrong. The subject never wakes up. And when Kira tries to stop the project, she becomes its primary target. On the run with nothing but her research data and a burner phone, Kira must expose the truth before the frequency goes global.
Because once the silence falls, nobody comes back.
