This week, we’re chatting with Rafer Roberts, who’s writing “Grumble,” which follows a double-crossing wiseass warlock who transforms himself into a pug, and his half-demon daughter, as they hit the road to escape all sorts of mobsters, interdimensional enforcers and the Jersey-est Jersey Devil that ever was. We also check in with Roberts' "Modern Fantasy" partner, artist Kristen Gudsnuk, at Camden Comic Con.
