The idea is taken from a friend's style of white elephant party and the "Blind Date with a Book" post floating around on facebook a few weeks ago.
Bring a wrapped book of any kind (used is more than acceptable!), and on the wrapped package write the GENRE and ONE SENTENCE DESCRIBING THE BOOK.
We'll then draw numbers and and choose books based on the descriptions alone. (Think any white elephant/yankee swap/whatever your regional name for gift swaps are.)
We'll enjoy Zeitgeist's beer selection while we swap some (hopefully) good books.
