The Unwanted Girl / A Marauder love story

For Slytherins she is the daughter of the slut. For her fellow Gryffindors except Lily Evans and her crew, she is the biggest embarrassment in Gryffindor. They all love to punish her for existing. For rest of the school she's invisible. But beneath the dorky exterior there lies a secret, an ancient power in her blood. To anyone who asks she says she's a half blood. Little do they know what she means is never what they imagine. Her father is more powerful than every sorcerer ever lived, for he's a Greek God..... This is the story of Daria Brizo Patil, daughter of the sea god.

When the story starts, they are only thirteen but they will mature as it progresses.
