Pig Tales by Marie Darrieussecq might be one of the better, and actually sensual, forms of tf media out there. Of course it's short, and dark, kinda like a Kafka story. Still some very good bits throughout.
Does anyone know if Circe by Madelline Miller has any good transformation scenes? Any other books?

Also there's the whole sub genre of were-romance. How many people actually have furry or tf tendencies anyway for that to be a mainstream thing?
