From our friends at Esquire:

    We put 250 napkins in the mail to writers from all over the country — some with a half dozen books to their name, others just finishing their first. In return, we got nearly a hundred stories. We present a sampling here — from lush to spare, hilarious to terrifying.

Napkin fiction is what the name says, fiction written on napkins. You can read dozens of napkin fiction tales here.
