About this book

One evening a girl named Louisa and her father Serk take a walk along a breakwater in a Japanese coastal town; hours later Louisa is found washed up on the beach, and Serk, who could not swim, is gone. From that vanishing, the novel opens outward across four generations and decades, tracing Serk's hidden life as a Korean born in Japan and the tides of twentieth-century history that swept up his family. Moving between postwar Japan, suburban America, and beyond, it is a sweeping, slow-burning story about identity, secrecy, and the things families never say.

Discussion questions

1. The novel opens with a walk on a breakwater and a father who does not come back. What was your first impression of that opening, and how did the mystery of Serk pull you through the rest?
2. This is a long book that ranges across decades, continents, and points of view. If the scope ever felt like a lot, whose story or which era kept you reading?
3. Serk is born Korean in Japan, becomes an immigrant in America, and keeps much of his past hidden even from his family. What did his lifelong secrecy reveal about him, and how did it shape Louisa and Anne?
4. This is a family where people can love each other without being kind. Did you find the characters hard to warm to, and did that make the book more honest or harder to sit with?
5. The novel ties one family's grief to vast historical forces, including the abductions at the heart of the story. What did it ultimately say about how history shapes the most private corners of a life?
6. Choi withholds and reveals across a fractured, time-jumping structure. How did that slow unspooling of the truth affect your reading, and what did you find yourself piecing together?
7. The story moves between postwar Japan, suburban America, and beyond. How did those shifting places deepen the book's questions about identity and belonging?
8. Did this remind you of another sweeping family saga, or another story about a secret that reaches across generations, in a book, a film, or your own family's history?
9. So much of this family's pain comes from what goes unspoken. Did the book make you think about the silences and secrets that shape families, and did anyone at the table see it differently?
10. Who would you hand this to next, the reader who loves an ambitious literary saga or someone drawn to hidden family history, and who might find it too demanding?
