Something causes most of the population to become werewolf-like creatures.
Hi! I'm looking for this fic where Draco is a werewolf and is in hogwarts. He's in a cage and hermione is his caregiver. They get close and when they "get together" he accidentally bites her. Years pass and he's on the run. Draco brings home a random muggle who's ironically dressed as little red. Hermione finds him after hunting him for years. Finds out she was pregnant but miscarried. The next morning Draco wakes up to a dead and bloodied hermione but it was all a dream. Happy ending. Anyone?
