内容简介：
A century-old mystery? Ghosts bent on revenge? Or hallucination? When high school teacher Frank Blaine is the only witness of what looks to be a murder during a Civil War reenactment, he attributes it to his imagination. The school year had ended badly. Now the stress of the job has caught up to him with the prospect of returning to work in a few weeks. When he encounters other apparitions, he begins to doubt his own sanity. Can this simply be stress, insanity, or are he and his fellow reenactors about to be plunged into a battle of supernatural proportions?
