Busy, bookish night! First, we're heading over to (if you work someplace conservative this link could be NSFW) Good Vibrations (603 Valencia Street at 17th) to have Stephen Elliot sign a copy of his new book, My Girlfriend Comes to the City and Beats Me Up, at tonight's party to celebrate its release. The party runs from 6:30-8:30, but we have to rush out sooner, so we can get to...

Berkeley's Black Oak Books (1491 Shattuck) by 7:30 tonight, to hear (scroll down) Ayun Halliday* read from her new book, Dirty Sugar Cookies.

Then again, if we're having too much fun at Good Vibes, we just might hang out and see Ayun tomorrow night at the Borders in Union Square (Powell, just up from Post) at 7, instead. Hey, we're unpredictable! Kind of.
