... "The Idiot" or "Karamazov," which are first and second, respectively, on my personal FD list.

The novel's introduction is a bit jarring, with way too many characters being introduced. The novel will be a splendid reread, though.

"Demons" also features one of the most vile literary antagonists I've ever encountered: Pyotr Stepanovich Verkhovensky. You'll see what I'm talking about.

I would recommend scooping up a copy with the formerly-censored chapter, "At Tikon's." I was pissed my translation (Pevear & V) had it as an appendix and not in the novel's body, as the chapter has serious implications concerning the book's ending.
