Tarot-medium Sophie Turner is back, and Boston is burning down around her as a string of serial arsons takes hold of the city. Her personal life isn't faring much better as Sophie makes some disturbing – and potentially dangerous – discoveries about her friends that undermine her trust in those closest to her. Worse, after suffering a psychic dry spell, the newspapers are speculating that she's a scam artist.
When a graduate student dies in one of the fires, Sophie spots a ghost at the crime scene. She thinks the spirit is weak, but finds out differently as the ghost gets inside her head, luring her into its past life. Sophie can only rely on herself, her ghost, and her gift to find the arsonist even as she becomes the killer's target.
