Topic: One book for the rest of your life
You're about to move to a remote, uninhabited island. Maybe you're rich and you want to be alone; maybe you've committed a horrible crime and you've been exiled. You're going to have all the supplies you need, but you can only take one book with you. Just one book for the rest of your life, to read over and over again or to use for toilet paper or whatever.
Which one do you take?
