I like Dostoyevsky, even though I read only The Brothers Karamazov and White Nights.
The Brother's Karamazov is my favorite book! It's great, and I love it dearly, I love Aljoshka, and the story in general.
From Tolstoy I've read The Death of Ivan Ilyich, because I've got a little book with this story as a gift. It was interesting, but I feel like I am not going to be fan of Tolstoy.
