Who can you trust if you can't trust yourself?

Early one morning, twenty-six-year-old Yu-jin wakes up to a strange metallic smell, and a phone call from his brother asking if everything's all right at home - he missed a call from their mother in the middle of the night. Yu-jin soon discovers her murdered body, lying in a pool of blood at the bottom of the stairs of their stylish Seoul duplex. He can't remember much about the night before; having suffered from seizures for most of his life, Yu-jin often has trouble with his memory. All he has is a faint impression of his mother calling his name. But was she calling for help? Or begging for her life?

Thus begins Yu-jin's frantic three-day search to uncover what happened that night, and to finally learn the truth about himself and his family. A shocking and addictive psychological thriller, The Good Son explores the mysteries of mind and memory, and the twisted relationship between a mother and son, with incredible urgency.
