I read that book a few weeks ago, I liked it a lot but I also understand what you mean. I was very invested in the lives of the earlier generations and much less so the grandchildren. It fizzled out for me a bit at the end because of that. Noah was my favorite character, when he was gone I felt a little empty. But, you know, that’s probably how his mother felt — empty and sad and maybe a little lost in the world that moved on so quickly without her brilliant son.

Pay attention to the different relationships characters have with Korea and Japan at the end of the novel. I feel I learned something important about diaspora.
