The sounds began in the silence.

Not a crescendo, but an infiltration—a soft, relentless scratching that seemed to originate not in the room around her, but inside the canals of her own ears. Cassandra lay perfectly still in the dark of her graduate housing apartment, the thin blanket a weightless shroud over her slender form. Her eyes were open, fixed on the ceiling’s vague shadows. She was awake. She had been awake for the last forty-seven minutes, according to the pale green numerals on the bedside clock. And yet the sounds persisted.

Scritch-scritch. Scrape. A dry, multitudinous friction, like the mandibles of a thousand insects working over stone. Then a softer, wetter gnawing. It was sound without image, a darkness given voice. It filled the hollows of her skull.

Between her legs, a low, steady throb had begun, keeping time with a pulse she could now feel in her throat.
