I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This gave me a good laugh. My favorite fanfics:
Art for the Sun a Scary by disillusionist9
A collection of warnings: characters and situations of silence.
The Perfect Cow by alafaye
Severus and Hermione start a horcruxes
Birds of a Saturday by SasuNarufan13
Harry Potter is drunk and discovers he is an alternate universe.
A Second Chance by DarkCorgi
Snape had a second thing, and that is better than anything for for the rest of his life.
I wouldn't be surprised if someone has already written something like "Birds of a Saturday" and "A Second Chance."
