Isis is a regular twelve-year-old girl, except she can see ghosts. Her friend Gray helped her fight a deadly ghost-eater in the summer holidays, so why is he ignoring Isis no they're back at school? Events take a strange turn when an accident on a school trip releases frightening apparitions. What have they got to do with the mysterious standing stone? And why do these visions seem to be following Gray? With the powerful Organisation trying to keep the answers secret, Isis will need all the help she can get - from the living and the dead - to uncover the astonishing truth.
