I almost didn't even notice this, but The Onion has a tiny notation for Monday, August 18th in their Calendar section that Sherrilynn Kenyon, writer of Marvel's Lords of Avalon: Sword of Darkness series, will be at Barnes and Noble in Clarendon at 6pm!
She is, in fact, an author of novels (under her own name and also Kinley MacGregor), and is promoting her latest book, Acheron.
While checking to see if this store had anything else interesting coming up, I found that Brad Meltzer, ex-DC resident, is coming back to the Barnes and Noble in Bethesda on September 3rd at 7:30pm to promote his latest, The Book of Lies. Schedule permitting, I'll definitely see you there!
(Mike here - Big Planet Comics owner Joel Pollack wrote in to say that Brad will also be at Politics and Prose in DC on Thursday September 4th at 7 pm.)
(Mike here again - Brad will also be ... in a grocery store? ... at Sterling, VA, Saturday, September 20 - 1:00 pm, Wegman's, 45131 Columbia Place)
