In a world where God is outlawed and flesh is currency, survival comes at the cost of humanity. When the Autarchy seizes seventeen-year-old Lee Chungho, they promise "healing" through transformation. What he endures instead is a living nightmare: cages of broken hybrids, mantras drilling into his mind, and a serum that twists him into something between human and monster. Branded with a serpent tattoo and forced to choose between obedience and annihilation, Chungho discovers both the horror and the temptation of his new body. Strength and rage surge where weakness once lived. Yet even as his humanity unravels, fragments of memory-his father's voice, his mother's faith-refuse to die. Hunted, reshaped, and torn between two identities, Chungho must decide what it means to be human when the world insists he is not. Is he victim, weapon, or something far more dangerous? The Duck with the Serpent Tattoo is a brutal, lyrical dystopian tale of faith, memory, and defiance-where even in corruption, redemption waits to strike.
