Question: As we all know, werewolves are humans that are transformed into ravenous flesh eating monsters. Some are [sentient](http://en.wikipedia.org/wiki/The_Wolf%27s_Hour), but most appear to be feral hunters of humans. Is there such a thing as reverse Lycanthropy? If so, what is the first story of an animal cyclicly turning into a human similar to the way humans turn into werewolves? I'm looking for the earliest example from the movies, TV, books, comics, or legends.

Answer: 
In the Terry Pratchett Discworld Novel Reaper Man, the character [Lupine](http://wiki.lspace.org/wiki/Lupine) is a wolf who, under the full moon, turns into a wolf-man.
In The Harry Dresden series, there is a book where a character is actually a wolf who takes human form by choice.

(Spoilers):

> 
>  In Fool Moon, Tera advises the Alphas, whom she met via the Northwest Passage Project, and agreed to teach them the ways of being a wolf.
>  At the end of Fool Moon, she left civilization for the wilderness. She was implied to be a wolf who could transform into a human, the opposite of a werewolf. One of the possible clues was that Harry Dresden could not Soulgaze her.
