I have not read The Idiot, but one of the books I listed in the "15 books of my life" thread (post 79--I'm not sure how to link to a single post) was Crime and Punishment, which I read in high school AP English. I really liked that book! It was one of my first introductions to "world literature."
I liked it so much I chose for my term paper a compare and contrast study between C & P and The Brothers Karamazov, which I also read and enjoyed.
