I just can't imagine my life without Dostoevsky and The Brothers Karamazov. I can spin off of that and talk about Crime and Punishment and Tolstoy. I could talk about other novels, but for me it's Dostoevsky. His sheer size and grandeur, his sacramentality, his ecclesiology, and his sense of the human predicament are as powerful as it gets. Can't imagine not reading the Russians.
