LU261 Booker Books: "Flashlight," by Susan Choi

Flashlight is a sprawling and ambitious historical saga that mines the "tides of 20th-century history" to explore the enduring ripples of family trauma. The narrative is set in motion during a summer in a coastal Japanese town, where ten-year-old Louisa and her father, Serk—a Korean émigré and academic—take a walk out on a breakwater. When Louisa wakes hours later, washed up on the beach, her father has vanished, an event that shatters her small family and leaves a void that reverberates across decades and continents.

The novel skillfully criss-crosses between the post-war Korean immigrant community in Japan, the rigid North Korean regime, and the quiet suburbs of America. As the mystery of Serk’s disappearance slowly unravels, the story expands to include Anne, Louisa’s secretive and increasingly isolated mother, and Tobias, the son Anne was forced to give up for adoption years earlier, who eventually drifts back into their lives. Choi balances these "intimate dramas" with "geopolitically bold" themes, moving from a poignant family mystery into a riveting exploration of identity, race, and national belonging.

Elegantly written and emotionally profound, Flashlight is described by critics as both a "capacious" historical reconstruction and a high-concept meditation on the "unreliable edges" of memory. A strong discussion angle for the group is Choi’s use of "narrative layers" and how the characters are shaped more by what they cannot see or remember than by the objective truths of their past.

Shortlisted for the 2025 Booker Prize and longlisted for the 2026 Women’s Prize for Fiction.
