I was also bested by Dune. I never finished "To Kill a Mockingbird" in high school, and have never had any desire to pick it back up. The most embarrassing/shameful is... "The Lord of the Rings: The Fellowship of the Ring." I love the movies, and I love learning about the lore on YouTube, but I just cannot make it through that book. "The Hobbit" was such a fun and silly little story, and I loved it! Fellowship just reads like those chapters in Genesis that you tend to skip over.
That's humorous.
