Callie and Clara were inseparable twins from the moment they could understand what siblings were. They have always been together and were both extremely excited when they got the same homeroom teacher their first year of highschool. They seem to have a pretty normal life at Stonebury Highschool until something goes wrong; terribly wrong. Clara is kidnapped and found later, dead. It is clear that she was brutally murdered, and her family wants revenge on whoever killed her. However, when Clara's ghost comes back and haunts Callie, it seems Callie has to be the one to get that revenge. Will Callie be able to track down the criminal without anyone knowing and put her twin's spirit to rest? Or, will she want to?
