Wordstock is back. If you don't know what that is, it's kind of a really big deal for books, book writers, book readers, and book enthusiasts. This year boasts an impressive list of guests: Aimee Bender, Jonathan Lethem, David Rakoff, and Ursula K. Le Guin, to name a few. $7 gets you for one day, $10 gets you in for both.
