The Genealogy of Evil, You-Jeong Jeong, Kyungran Choi, Pierre Bisiou

Yujin, twenty-six, wakes up one morning to the smell of blood.
Until that day, he was a model son who adhered to all the rules of an abusive and anxious mother. A mother who, at this very moment, lies at the foot of the stairs, her throat atrociously cut from ear to ear.
What happened last night? Only fragments of strange images emerge from Yujin's consciousness, and his mother's anguished cry. But was she calling for help? Or was she pleading?
To find the key that unlocks his memory, he must go back sixteen years, to when it all began. To rediscover the initial, unthinkable, unbearable scene. Sixteen years of secrets, silence, a life controlled down to the smallest detail, until everything spirals out of control.
But once the forbidden boundary has been crossed, there is no turning back.
This disturbing and haunting thriller, of exceptional psychological acuity, follows at a breathless, electric pace, the radical transformation of an ordinary young man into a dangerous predator.
