Paige is not your normal teenage girl. Her only friend is a girl who is dead. Paige is the only one who can see her too. The world around just thinks she's crazy and they call her Bellevue Kelly because of it. After a little while a new kid named Logan comes to her school, and starts borrowing her pink pens trying to get to know her. Then four new students come in to the school, and they all don't really like Paige. The thing is that every time Paige talks to her dead friend it opens a rift in between the real world and the dark world where all the demons are. One of the four new kids confronts Paige and turns into a demon right in front of Paige. Thankfully, Logan finds her and the demon and kills it. After that encounter Logan trains Paige in the ways of demon slaying. The only way for Paige to not fall into the dark world is to kill the other three demon that invaded the school with Logan's help.
