unexpected Leviathan "fanfic"

So Scott Westerfeld held a poll on his blog regarding one last illustration from the Leviathan-verse, and the artist drew it, and then Westerfeld decided he needed to write a story to go with it, which he describes thusly: "it's really more fan fic than a long-lost chapter. It's full of fan service and cross-dressing and all sorts of shippy stuff. And yet: By my authorial authority, I DECLARE IT CANONICAL."

Yay.
