There is no door. There is no sky. There is no day that ends and no night that begins. Only a box of black stone, ten strides by ten, and a labor with no purpose but to be endless.
Kasim stops trying to count the days somewhere in there, and starts counting his breaths again instead: the one inheritance the dark cannot confiscate.
He is not alone. A thing that was once fire dims beside him. A thing that was once proud folds itself smaller every year. And a thing that calls itself a friend keeps offering him the one bargain that ends all bargains: surrender, and the weight stops.
Kasim refuses. Not because he still hopes; hope rots in a place like this. He refuses because he is owed something, and a debt, unlike hope, does not die of waiting.
Somewhere past the labor, past the guards that glow faint violet in the dark, something far older than his captors has noticed him. It has been waiting far longer than he has. And it is about to tell him exactly what he is.
The Lightless Years is the second volume of The Thread That Would Not Break: a descent into the timeless prison built to unmake a man, and the quiet, furious arithmetic of the one thing it cannot take from him.
