Speaking of books that made a permanent impression on me, The Good Earth did. It made a noticeable and long-term impact on my perspective and values. If I remember correctly, I read it on recommendation from my mother.
I always thought Pearl Buck was a funny name… for a man. I never read anything biographical about this author until today. And so, never learned that this author was a she. Today, I rectified that (via 3qd). If you haven’t read about her – or more importantly, read her most important work, you should.

I loved The Good Earth and the two sequels that came after it.
Good stuff.
Aww man. Twin sons of different mothers. I read The Good Earth as a child at the urging of my mother. But I always knew Pearl Buck was a she. Mama told me that before I read the book. And it is very, very good stuff.
