Flashlight by Susan Choi: A Gripping Family Mystery Susan Choi's latest novel Flashlight , published in 2025, centers on a Korean-American family's unraveling after the mysterious 1978 disappearance of the father, Serk Kang, during a beach walk with his daughter Louisa in Japan.

  • The Guardian notes its "big, bold" scope, stretching across continents in fragmented illuminations like a child's torch in the dark.
  • LA Times review calls it a beguiling mystery unpacked with Franzen-esque detail and Zola-like caustic voice.
