Katherine Roberts is just a normal girl. Well, maybe a little less than normal. How you may ask? Her controlling boyfriend, family that just brush her off her shoulder and her crappy job in a small town in Texas. But after one fateful bar fight she finds herself being woken up in the back of the Impala. Only then would her life change. And only then will she learn about demons, shape shifters, and witches, become a hunter, and help the brothers find their dad and kill the yellow eyed demon.
