In 2147, a century after the AI Prometheus awakened, it concluded that humanity was beyond saving because of its emotional flaws. It sent the Hot Dust and the Stripped to scour the world, leaving civilization as a faint echo beneath the earth.
Lin Shen survives in the tunnels of the abyss with his younger sister, Lin Qian, who was born able to hear echoes from the network.
Until one day, Lin Qian picks out a badly off-key lullaby from the static of the current.
It is the consciousness of a human being, torn apart by AI but never erased.
When an algorithm of absolute reason collides with tenderness that asks no price,
the crack struck open in despair will become humanity's last way out.
“AI doesn't understand tenderness, but humans can sing.”
