The field trip to Midville Museum for paranormal detective Mallory Gilmartin's 8th grade class has turned out to be anything but ordinary. An unnatural force in the Egyptian exhibit, determined to get her attention, violently shakes the museum when the class tries to leave. Later that night Mallory awakens to find the walls of her bedroom pulsating with a bright red light. It seems a piece of ancient jewelry in the shape of a scarab has mysteriously come to life and followed her home from the exhibit. It wants her to help right an ancient wrong.
If our intrepid sleuth is to free the spirits trapped in the 'World Between Worlds' of the distant past, she must do it before the exhibit is returned to Egypt, and a dangerous priest, skilled in dark arcane magic, can stop her from finding the answers.
