Neutral Territory [A Harry Potter fanfic]

Sky Laken never fit in in the Muggle world. Her friends were cold hearted and they always seemed to have on and off relationships. They thought she was a freak, a nobody. Strange things happened that almost cost their lives. Just because of her. And when life gets worst, she loses her job as an assistant for her friend Emily. 15 year old Sky was lurking on the streets, alone, hoping a small miracle will happen. And sure enough, a miracle appeared. Professor Dumbledore appeared out of the blue and took Sky to Hogwarts so she can get into training. But what she didn't know, her parents were killed by her father, Voldemort. Or as He-Who-Should-Not-Be-Named as the passive people said. She was horrified as she found out who he was, and including that he is evil and is her father. And so she knew, that the mark, the Dark Mark on her forearm was from her father. She had it ever since she was a baby. It was almost like a marking of pure evil to her.
