It's a Joanna and Antryg story, and that was enough for me to scoop it up without a second thought. (It's sold only via the author's website, I believe. A bit expensive for a short story, but JOANNA AND ANTRYG, EEEEEEE!)
And it is indeed a story in the same vein as The Silicon Mage, including technology appropriate to the time period. (Which very nearly makes it historical fiction in these days of smartphones and the World Wide Web! ...even though I would adore seeing Antryg examine an iPhone or play a little World of Warcraft. But anyway!)
It being a short story, anything else would be a spoiler. If you're a fan of this pair, you want the story. If you're not, oh-well.
