What is the trouble with ghosts? That's exactly what Arabelle Scott is about to learn when she's sent away to boarding school after accidentally showing her psychic power. The power that she would do anything to get rid of. When she meets Colin, a boy with similar powers, they reluctantly unite to be friends and discover their powers together. And everything was perfect for a minute. Until Rowena showed up, a murdered girl with a tragic past. She threatens them with death if they can not solve hers- because the killer is in the school. The trouble with ghosts is that they don't let go of the past. And they won't let go of you.
