S The fine people at HBO, makers of the new scifi vampire show True Blood, are throwing a party in Chicago next week. And you're invited. There will be cocktails, hors d'oeuvres, and a special showing of the premiere of Alan "Six Feet Under" Ball's new series. Judging from what we've seen of True Blood, it's going to appeal to Buffy fiends and Forever Knighties alike. Plus, it'll pull in Desperate Housewives fans, just for good measure.
