I've got several classics high on my TBR list.
The Virginian by Owen Wister
The Virginian is set just down the road. It's one of those books that I feel as a Wyomingite, I need to read.
Silas Marner by George Eliot
And, for when I'm feeling really motivated: The Brothers Karamazov by Fyodor Dostoyevsky. I have good intentions with it, but it'll probably sit on my shelf for years.
