Mine is Anna Karenina. My mom tried to get me to read it for years but I wouldn't because it looked lame. I finally did back in 2014. I never take notes on books I read but I did with this one because it was so long and there was so much going on. I loved it. Levin might be my favorite character from any book.
East of Eden is in my top five. I would need to think of the others.
