I just came from the Ogre and there was a signing there today by the creators of a book called Scarlet Veronica, a horror comedy from Ape Entertainment. I haven't read it yet, but it looks like it'll appeal to Buffy fans.
Tomorrow, they'll appear at Hobby Central in Delaware and back at the Ogre on Saturday. Unfortunately, their website doesn't list times, so you'll have to call ahead.
