All Susannah Simon wants is to make a good impression at her first job since graduating from college (and since becoming engaged to Dr. Jesse de Silva). But when she's hired as a guidance counselor at her alma mater, she stumbles across a decade-old murder, and soon ancient history isn't all that's coming back to haunt her. Old ghosts as well as new ones are coming out of the woodwork, some to test her, some to vex her, and it isn't only because she's a mediator, gifted with second sight.
