I'll be attending AwesomeCon in Washington DC for one day only, on Friday, March 30. I'll just do one, two-hour signing at the ComicSketchArt tables in Artist's Alley in the afternoon from 2-4. (Don't know the exact table number, but I'll be near Scott Snyder, Tom King, etc.) somewhere in rows O or P.
I'll mostly just be there to sign, but I'm planning to bring ten copies of THE ORACLE YEAR in its final, hardcover version - five days before street date, since it's not actually out until April 3! Swing by if you want one.
