Reeling from the dual deaths of her estranged father and ex-fiancé, Genevieve Tompkins has dropped out of her PhD program in New York City and is looking for a chance to start over in Wilton Springs, a faded Victorian spa town in upstate New York. Utilizing her background as an archivist, she is hired to catalogue the papers of the prominent Wilton family, who trace their lineage back to the founders of the town. But as she digs into their records, Genevieve discovers that the family's pharmaceutical business and their personal lives have been fraught with a history of tragedy. She also uncovers a series of disturbing disappearances and suspicious deaths among the women of the town.

Three centuries earlier, Wilton Springs was the site of a brutal witch trial—a fact which someone has gone to extreme lengths to erase from historical record. As Genevieve explores the connections between the modern disappearances and the town's ugly past, she becomes entangled in a web of conspiracy, where the line between superstition and reality begins to blur, and she fears she may become the next woman to go missing from Wilton Springs . . .
