Not a book, but I just read Waiting for Godot. I'm sure it's better on stage, but I really liked it. Heart of Darkness, though very verbose, is fairly short. The Old Man and the Sea is a quick read too. Course, I'm probably listing books that y'all read at least 20 years ago.

Bartleyby.com has quite a few short stories in their files. That's where I read the Melville's story that inspired the title for the website. That was an enjoyable read.
