Paradise is an illusion, and the progressive, experimental city of Nysa Serin was living on borrowed time. The winter festivities that should have warmed everyone's heart take the contorted face of a feast of fools. Despite their knowledge, Selen, Louis, and Lissandro are swamped by events. Falling one after the other, the sick litter the streets of Nysa Serin. A natural pestilence? The vengeful hand of the gods? Turned to ashes, Louis's dreams slip through his fingers like a shattered cathedral of sand.

Jeopardizing its fragile stranglehold on the crown, the royal couple leaves for a desperate mission while, trapped inside the walls, the citizens strive to survive. Though the clock ticks on, in sickness and fear, the tensions surface and friendships are tested.
