The Psalm of the Black Tide

"The silence of the Hebrides was not an absence of sound, but a holding of breath a pause before a scream."

The ocean isn't crashing. It’s conducting.
Hebrides, 1922. Disgraced musicologist Arthur Pendelton travels to the isolated Isle of Morne for one final chance at redemption. His goal: to record the "Mourning Song," a local legend said to rise from the sea caves during the winter solstice—a sound so mournful it drives whales to beach themselves.
But Morne is a place where the wind doesn’t blow—it whistles through the porous black stone of the cottages like a flute. The villagers possess skin that looks too wet for the dry air, and they don’t speak; they hum.
When Arthur slows down his wax cylinder recordings, he discovers the terrifying truth. The crashing waves are hiding a complex, mathematical choir. It is a biological command signal rising from the abyss, a frequency designed to rewrite the DNA of everything it touches.
As the Solstice approaches, Arthur begins to change. The fresh water tastes like ash. His bones are softening. And behind his ears, the skin is beginning to split open.
Trapped by a storm and surrounded by a cult that worships the silence of the deep, Arthur must decide: destroy the recording and die a man, or play the song and wake the god waiting beneath the crust.
