Pachinko by Min Jin Lee

In the early 1900s, teenaged Sunja, the adored daughter of a crippled fisherman, falls for a wealthy stranger at the seashore near her home in Korea. He promises her the world, but when she discovers she is pregnant—and that her lover is married—she refuses to be bought. Instead, she accepts an offer of marriage from a gentle, sickly minister passing through on his way to Japan. But her decision to abandon her home, and to reject her son’s powerful father, sets off a dramatic saga that will echo down through the generations.
