In a world flipped by the Inversion, humanity clings to the underside of vast Sky-Forests, where roots hum with ancient grudges and the endless void hungers below.Mira hears the trees first, a restless whisper turning to a command: Prove your worth, or fall. As Climbers rise from the Rootless Ground, pale horrors with too many eyes, the forest reveals its truth: humans are the poison branch, tolerated only until severance.Torn between symbiotic mercy and devouring judgment, Mira must choose to merge with the canopy's will or face exile into the abyss. But the trees remember every axe and flame. Mercy has limits. One wrong step, and the hum becomes a scream.Atmospheric cosmic horror meets post-apocalyptic symbiosis in this gripping tale of inverted survival.
