The Brothers Karamazov...The Idiot (which is interesting for what it says about pre-revolutionary Russia...there was this attitude of hate-all-things-Russian...so familiar, here in the States as the same attitude prevails at times...hate all things American...too...but I better not spoil it for you...some great scenes on a train) I think these two are much better than Crime & Punishment, that I've also read. I can't recommend Dostoyevsky enough.
Don Quixote...Cervantes story might be more than four-hundred years old, but it is story...thoroughly enjoyable. There's a line or two in this one I've remembered: Virtue is persecuted by the wicked more than it is loved by the good. Nothing's changed. Friend to friend no more draws near and the jester's cane has become a spear. Sounds grim, but there is a great deal of humor in this story.
Anna Karenina, Tolstoy...maybe you've seen the movie? another good long read.
Anything by George Eliot. Her stories have as much psychological realism as Dosty's...if not more. The Mill on the Floss...Middlemarch...Silas Marner
Ibsen.
The Bard...but if you can find recordings that is so much more enjoyable as you get more than just his words...you get feeling, context, tone.
Give the Brothers K a shot...if you don't like that, ignore the rest of what I've said.
