In a future where the government regulates sound through ear-implants called Regulators to maintain "peace," Iris lives in a world of artificial, muted calm. When her device breaks, she is suddenly flooded with the raw, chaotic beauty of real sound—the wind, the grit of city streets, and the rhythmic heartbeat of a world she never knew existed.
Teaming up with a group of underground rebels, Iris discovers that the silence isn't for protection, but for control. As she masters her unique ability to perceive frequencies, she must infiltrate the city's central Spire to broadcast a "dissonance" that will shatter the digital trance and wake the population before the Oversight erases human curiosity forever.
