Just to recap for locals making weekend plans:
The launch party is at East Side Story at 6 p.m. I suspect actual doings won’t start until 6:30. You can pre-purchase copies here (and that’s the only way for out of town people to get books that I know of at the moment). You don’t have to pre-purchase copies. Plenty will be available at the event.
But once they’re gone, they’re gone.
