Apparently, the series by Sarah Monette that begins with
Melusine is referred to collectively as "The Doctrine of Labyrinths Series". Awesome!
Nearly-completely unrelated, have a running list of all the DoL fic I've been able to find. None of it is entirely worksafe, I'd say, but nothing's outright porn either
more's the pity.
First, by scribblemoose at Yuletide. Mildmay visits a whore, and Felix freaks out.
At the Hands of the Wicked, by Quasar, also at Yuletide. Mildmay hears a ghost, Felix has a dream, and Robert loses his rings.
Something to Look Forward To by Greensl33ves at Fanfiction.net. Felix gets drunk, falls down, and remembers his promise--much to Mildmay's dismay.
Scars, by Greensl33ves at FF.net. Mildmay gets five bruises, and his scars get some attention. Felix starts drinking.
Appassionata, by Greensl33ves at FF.net. Gideon is badly jealous of a man he likes, Felix has issues with blood and dominance, and Mildmay thinks everyone's insane.
Weight of a Promise by Greensl33ves at FF.net. Short drabble. Felix is unaccustomed to resisting temptation. Mildmay is a damned good reason to practice.
Ficlet by ifIcouldfly at porn_battle. Felix has insomnia, and Mildmay should remember to keep his nightshirt pulled down.
