Happiness Falls by Angie Kim is the story of how a close-knit Korean American family is rocked by a sudden disappearance. Narrated by the witty, fast-talking 20-something daughter Mia, the book begins when Mia’s father, Adam, and younger brother Eugene go missing. When 14-year-old Eugene returns home bloodied and alone, it raises more questions that can’t be easily answered, particularly since Eugene is neurodivergent and nonverbal. The search for Adam raises a series of possibilities--was he suicidal after being diagnosed with a terminal illness? Having an affair?--the book also delves into the dynamics of the family and how they shift in light of Adam’s vanishing.
