The Union provides. The Union protects. The Union lies.
Fourteen years of "temporary" emergency measures have turned the world into a tiered cage. While the Inner Zones glow with a seamless, untouchable light, Maya Hart survives in the blackened lungs of Zone 9, spending her days avoiding the scanning eyes of patrol drones.
In a single night, thousands disappear. The Department of Faith calls it a miracle and gives it a name: The Vanishing. They claim the missing have been chosen for their obedience.
When Maya’s brilliant brother, Caleb, vanishes, he leaves behind something the Union can't explain: a hidden notebook filled with power grid coordinates and a radio receiver that whispers a terrifying truth.
Accompanied by a mysterious transfer student with too many secrets and a scavenger who knows the city's hidden veins, Maya must uncover what lies at the center of the Union's greatest secret.
As her Harmony score spirals toward a critical threshold, Maya must uncover the secret of Project ECHO, because in a city built on a lie, the only thing more dangerous than the dark is the light that powers it.
