Great news that you're likely to be there, Mark. I'm going to be launching certainly one and in all probability two books at Eastercon, and by the look of things, the launch party is likely to be on the Friday, immediately before the official opening ceremony, so come along for a free glass of wine or two!
Only problem is that the program isn't kicking off until Friday evening, so it seems doubtful they'll be running too many full panel items on the Friday -- they're more likely to happen on the Saturday, Sunday and Monday.
