As a child, Rue Winchester had loved ballet. She had danced all day, every day, and her love for it never wavered. She almost stopped dancing when her father died in a tragic car accident, but by then her younger sister had been born, and Duck Winchester had loved to watch Rue dance, so Rue kept on going.
Rue Winchester is now a hunter. Years ago, her mother had discovered that the accident that killed her father had been the work of a demon. Yes, an actual demon, and not the only one involved either.
Due to her mother's obsession with finding and killing the demon who had committed this crime, Rue had started "hunting" with her mom at the age of six. Hunting, was, well, hunting, but not deer or rabbit or duck. Hunting was killing monsters and demons and any evil she could get her hands on. Rue Winchester no longer dances. Rue Winchester is now alone.
Duck Winchester had never been good at ballet, but she had danced it anyways, and she still dances to this day. She used to hunt with her sister, but when their mother up and left them to hunt on her own, she abandoned the lifestyle she hated so much and left for college. She then went to Stanford University in California where she lived a happy college life. She had good grades, wonderful professors, an amazing boyfriend, and a nice apartment, but in a blink of an eye, suddenly everything had changed.
Duck Winchester's boyfriend is dead, killed in the same way as her father. Her mother and sister, Rue, who she hasn't spoken with in ages, are suddenly on her doorstep saying they've found evidence that her father might still be alive.
Devastated by the recent turn of events, Duck has wanted nothing more than to jump back into the life she once knew, when it was all just clumsy dancing and happily messing around with her sister in the back of their mom's '67 Chevy Impala. But now that her only family has made a reappearance, she has no choice but to accompany them in the search for more clues about her father.
