Mary has a gift to hear ghosts. As a result, she is a Pariah in her school given the nickname 'Scary Mary'. A new boy in town, befriends her and she is excited he seems willing to see past all that. Then an impromptu seance at his house changes everything. A malevolent ghost causes all sorts of trouble and Mary is blamed for it. Now things are worse than ever and Cy wants nothing to do with her. Yet she feels she needs to do something about the ghost before Cy or his family are hurt. 
 A quick, fun read. What I like the most is that Mary is no victim and will fight like a hellcat when she needs to.
