The Girl Who Lived (HP/SPN)

Born a Snape.
Raised a Winchester.

Eileen Lillian Mary Snape-Winchester. The daughter of Severus Snape and Lily Evans and the sister to the Winchester brothers. When Elena receives her Hogwarts letter what she doesn't know is what Snape has shielded her from for the last eleven years and that is her title and fame as The Girl Who Lived alongside her half brother Harry Potter. It's time for the wizarding world to meet the two remarkable and lucky children who escaped Lord Voldemort's clutches all those years ago and in the process destroyed the Dark Lord almost completely.

But will Elena and Harry become allies or enemies?
Two destined for something they can hardly even imagine.
Harry Potter the boy who lived.
Elena Winchester the girl who lived.
One child is Voldemort's legacy and the heir to his entire empire of darkness while the other is his destruction and the weakness he never wanted!
