Unity Con (A Spade/Paladin Conundrum), by Kristine Kathryn Rusch

WMG Publishing, November 2021

Spade is in Garland, TX, hanging out with people he likes instead of going to Unity Con, a convention he has sworn not to attend, because it's been organized by a group, or rather two groups, of people at the heart of a major brouhaha around the Hugo Awards a few years ago. They've now decided to start a new convention, uniting fandom--and they're all sf pros, not the fans these two groups look down on as mere amateurs. It isn't just that Spade doesn't like most of these people. It's that he sees a disaster that could create problems for all convention-running fandom if they have anything to do with it.

Spade is staying away. Far away.

Then he gets a call from Paladin, who is at Unity Con.

There's been a murder. 

At Witt's End (A Spade/Paladin Conundrum), by Kristine Kathryn Rusch

WMG Publishing, October 2018

Spade is back and this time the problem he faces is conducting a memorial for a recently deceased BNF (Big Name Fan) who never wanted any memorial, along with auctioning off the man's fabulous collection of science fiction fandom memorabilia, in a part of the country that doesn't have large enough conventions to be good fits for auctioning off such a large collection.

This fan, who like Spade went by just one name, Witt, is also the second fan this year, of Spade's general age, state of fitness, and diet, to die of diabetes. Spade is very resistant to changing his lifestyle and diet, and hasn't been diagnosed with diabetes yet, but he's starting to get the message. That, as much as losing an old friend, is making him depressed and cranky. And that's before another fandom detective, Paladin, pull him out of the room, and tells him the extremely valuable (within fandom), absolutely unique set of fanzines, has been stolen from the adjoining room, where Spade has set up multiple security cameras and made the fanzines really hard to notice.

Plus the joy of science fiction fandom and geek culture.

Elle Wittimer isn't just a dedicated fan of cult sci-fi show Starfield; she's also the daughter of two big name fans. Her mom and dad met at a convention, and her father was one of the founders of what's now one of the biggest conventions, Excelsicon. But her mother died, and her father remarried, giving her a stepmother and two stepsisters. Then her father died, too.
