Read "War And Peace" because it's the longest classical literature ever made. All the other ones that are longer are not considered classics. I truly regret the day that I would ever consider "Atlas Shrugged" to be a great work of literature (it is longer, BTW). If you're going to read a neverending book, make it this one. Before this, "The Bible" was probably the longest book I ever read, a thousand something pages.
