The question of whether nurture or nature creates a serial killer is at the center of the newest thriller by bestselling author Mi-Ae Seo. When the criminal psychologist Seonkyeong interviews the infamous killer Yi Byeongdo, she is unwittingly reminded of Haeyong, her stepdaughter, who has recently begun to live with Seonkyeong after her grandparents perished in a fire. The parallels between Byeongdo and Haeyong indicate a shared past of abuse, instigated by those who were supposed to care for them. Through unforgettable imagery Mi-Ae Seo ponders the irreparable consequences of child abuse, and the legacy of broken families. —K.L.
