In a world governed by the Sanctum, seeing the truth is a death sentence. When Kael is taken for "Correction," she expects her mind to be scrubbed clean—a return to the blissful ignorance of the masses. Instead, she is pushed deeper into the breach, where the fabric of reality is fraying into "threading."
Kael is no longer a woman; she is Subject Thirteen. As her memories dissolve and her body unspools, she realizes the horrifying the world isn't being protected from the Veils. It’s being fed by them.
Now, a lone researcher must decide if she will follow the Council's protocols or listen to the four pulsing lights in the dark—the last remnants of a soul that refused to break.
In the Sanctum, the only thing more dangerous than the dark is the light of an opened eye.
