There are lots of secrets that 105-year-old Hak Jeonga has carried with her throughout her life. But even after she dies, there's still one big one – generational curse included – that she must resolve. Jimin Han's new novel, The Apology, follows the family from South Korea to Chicago to right some of the wrongs that have happened over time. Han tells NPR's Eyder Peralta how she was influenced by her own family's experience of longing and separation following the Korean War, and why Korean shamanism influenced this story of immortality.
