Prologue
Dean and Sam Winchester were hunters; their father had been a hunter and had trained them to hunt. So that was what they did; they tracked the demons, ghost, vampires, werewolves and everything else and either killed it or sent it back where it belonged. Then Sam had been killed and Dean did a deal with the crossroads demon, giving his life to have Sam back. The demon had given Dean a year, a year to do whatever he wanted and then his soul was gonna go to hell. Six months left and they had finally decided to track down a way to save Dean. They knew exactly where they had go.
Not many people know that the Winchesters' have a cousin. She was sort of a black sheep to the family because her mother, Rita, was John's sister and her father was a demon. The demon had possessed Rita's husband on their wedding night and gotten her pregnant. Because of this she had only a few of a normal demons weakness' she is burned by holy water, crucifixes mildly agitate her skin like a mild allergy and silver. Although she can enter churches, cross salt lines. She was also a valuable asset; she can cast glamour's and summon things. This meant that she is able to hide weapons wherever the brothers needed her to. Though because of her mixed genealogy she was a marked target, demons don't take kindly to half-breeds of any sort.
