Jim Brown reseñó Kokoro de Natsume Sōseki (Penguin classics)
two books in one
The introduction to my edition says that the third part of this book was initially its own thing, and that makes a lot of sense. The first two parts of the book offer a kind of nest for the last part of the narrative.
An intergenerational story, which seems to be a trend in the 20th Century Japanese fiction I've read. Bleak also...kind of another trend. I have tended to link both of those things to WWII, but this one was published in 1914, so that theory doesn't hold up.
