And the number is....3!
I will therefore be reading And So Flows History, by Hahn Moo-Sook. It's a three-generational Korean family saga that starts in the late 19th century and continues until, I think, the end of World War II. It was published in 1947 and does not include the ideological battles that turned into the Korean War.
Hahn Moo-Sook was quite a young woman when she wrote the book; she must have been about 30, and a young mother, when it was published. Her daughter, Young-Key Kim-Renaud, is the translator. (To clarify, on the book, Hahn's name is written in the Asian way, and Kim-Renaud's in the Western way.)
Should be interesting! I'm supposed to finish and post by April 30th. Surely I can manage that. And it will count for South Korea in my Read All Around the World Project too!
