​Zack Vance spent his life as the world's foremost hostage negotiator, a master of reading and controlling emotion. Now, in a world shattered by a terrifying Sensation Plague, his expertise is a curse. The Infected don't track noise or light; they hunt feeling. Any intense emotion,fear, rage, or even joy is a beacon leading them straight to the kill.

​To save his daughter, Chloe, Zack taught her the ultimate survival technique: Zero Emotion,a cold, absolute stillness of the soul.

​But when a desperate mission leads them into the heart of a military conspiracy, Zack discovers a terrifying truth: the plague is not a natural disaster, but a geopolitical weapon designed to enforce global silence. The only place left to fight is a hidden sanctuary where survivors have already embraced a tyrannical, emotionless void.

​Now, Zack must race against time to destroy the Anti-Antidote,a chemical agent designed to erase the very memory of love before the soldiers, the scientists, and the Infected silence the world forever.

​His final choice: maintain the silence that saves their lives, or embrace the terrifying chaos of human affection to reclaim his daughter's soul.
