Susan Choi joins Kate Wolf and Medaya Ocher to speak about her new novel, "Flashlight." An epic story that spans multiple generations of a single family, the book is an astute exploration of identity, migration, memory, kinship and the irrepressibility of the past. It begins in the wake of the mysterious disappearance of a young academic named Serk. An ethnic Korean, who was raised in Japan and decided to continue his studies there when his family returned to Korea after WWII, Serk later moves to the US and marries Anne, who is also estranged from her family and has her own secrets. Their daughter, Louisa, is with her father on the night of his disappearance, from a beach back in Japan, where the family has come for Serk’s year-long academic appointment. Washing up on the shore in the morning, Louisa has little memory of what has taken place, and it will take her many decades, and the course of the novel, to discover the truth.
