A thrilling, globe-spanning novel that mines questions of memory, language, identity and family

One evening, 10-year-old Louisa and her father take a walk out on the breakwater. They are spending the summer in a coastal Japanese town while her father Serk, a Korean émigré, completes an academic secondment from his American university. When Louisa wakes hours later, she has washed up on the beach and her father is missing, probably drowned. 

The disappearance of Louisa’s father shatters their small family unit. As Louisa and her American mother Anne return to the US, this traumatic event reverberates across time and space, and the mystery of what really happened to Serk slowly unravels. 

Flashlight moves between the post-war Korean immigrant community in Japan, to suburban America, and the North Korean regime, to tell the astonishing story of one family swept up in the tides of 20th-century history. 

Flashlight was shortlisted for the Booker Prize 2025.

What the judges said

Flashlight is a sprawling novel that weaves stories of national upheavals with those of Louisa, her Korean Japanese father, Serk, and Anne, her American mother. Evolving from the uncertainties surrounding Serk’s disappearance, it is a riveting exploration of identity, hidden truths, race, and national belonging. In this ambitious book that deftly criss-crosses continents and decades, Susan Choi balances historical tensions and intimate dramas with remarkable elegance. We admired the shifts and layers of Flashlight’s narrative, which ultimately reveal a story that is intricate, surprising, and profound.’

What the critics said

Beejay Silcox, Guardian 

‘Choi is one of contemporary literature’s great demolition artists, and her emotional foundations hold. She can build as well as she detonates. Choi gives her cast the room they need to live; to be more than vessels for political wrangling… Like the best of those early-00s novels, Flashlight is all kinds of big: capacious of intent and scope and language and swagger.’ 

Catherine Taylor, Financial Times  

‘Susan Choi’s sixth novel takes a little-known and appalling aspect of Japanese-Korean history and fashions it into a rich generational saga that teems with intelligence, curiosity and, in terms of reading, sheer pleasure.’  

Ron Charles, Washington Post 

Flashlight is severely allergic to summary, so watch what you read about it. Even categorizing this story as a mystery risks prematurely exposing the novel’s intricate structure to too much light. It’s catholic in its genre, shifting deftly from domestic drama to international thriller, from academic satire to bildungsroman. But what can be safely revealed is that Choi is writing about people who struggle and fail to find a stable sense of identity in a shifting world conspiring against them.’
