The Demon Ticket

When a demon intrudes the teen life of January Johnson [nick named JJ], based on a deal she has with her mother, things take a turn for the worst. She's faced with life changing decision, and urges to find out more about her mothers past.
JJ keeps a journal that soon becomes the door way for the demon to enter. Never being able to get away, she learns how to live with it, while still hiding it from her mother and best friend. But she can't hold up the wall forever. When the demon problem gets worse, her friend starts to act up, revealing she's hiding something too. But something completely opposite from JJ.
