Marking this one as DNF because aside from the Iron Druid story, I haven't found any of these entertaining. I think it's mostly because the carnival theme doesn't feel like it's truly there, and some stories treat the carnival as the vaguest of backdrops for a story that might fit the bill.

I read up to "A Duet with Darkness," so if there are other stories I didn't get to that you think I must check out, please let me know and I happily will.
