Once There Was A Darkness: Year One by C_A_Campbell
Rated: 3rd-5th Years [Reviews - 74]
Summary: Winner of the 2008 QSQ for Best Female Original Character.
Twelve years ago, one man's life was changed forever by three simple words: “Severus, I'm pregnant.”
Now, twelve years later, a girl will embark on the journey of a lifetime. But life at Hogwarts for a first year is far from simple, especially not when she's in the same year as Harry Potter. She will face enemies, choices and danger, while struggling to deal with her past's dark secrets that, after all these years, still threatens to destroy her.
One girl's journey. One man's desperate search. One last chance for Severus Snape to find the daughter he lost.
Snape seems... rather wildly out of character here.
