I have no doubt that even after dying, Jolee would be just as ornery.
I have my little ideas for another story with the trio, but I have to sit down and outline a bit and figure out where I want to go with it, now that I'm beginning to have a vague clue about writing something as long as this. I still have the revisions of the chapters to do for KFM (I'm at ch. 16 there and working on 17), and my beta-reader is very good and makes me work hard to make them better--that involves almost as much time as writing the initial chapters, sometimes more. I hate leaving projects unfinished, even if it takes awhile to get them done, and I'm learning a ton revising those chapters, so I want to make sure to finish that. A couple of them would never forgive me if I left them hanging in the middle of the story.
Mik'oth of course would have to make a return appearance. He's too fun not to have around. I don't know that I could stand to have His Smarminess join the trio and become a main character--he's better as an occasional contact. Otherwise, it'd be sort of like having mounds of icing on the cake instead of nice thin layer that doesn't overpower.
