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.
