I know this is rather last minute, but just in case you haven’t heard, Discworld-series author and Knight of the Realm Sir Terry Pratchett will be speaking at the National Press Club this Friday, 7pm, October 14, 2011. You can buy tickets here.
Pratchett will be discussing his latest novel, Snuff: A Novel of Discworld. You can pre-order copies of the book when you purchase tickets for the event.
If you have never attended an event like this at the National Press Club, I highly recommend them. Just be sure to get there early–long lines are guaranteed.
