When her widowed father exiles sixteen-year-old Katy Jessevar to a boarding school in Whitfield, Massachusetts, she has no idea that fate has just opened the door to both her future and her past. At school her fellow students instantly despise her, and Katy pieces together clues to learn that Whitfield is the place where her mother committed suicide under mysterious circumstances when Katy was just a small child. Like many of the New England families in Whitfield, her mother was from an old witching line, and Katy discovers that she too possesses special powers. With dark forces converging on Whitfield, it's up to Katy to unravel her family's many secrets to save the boy she loves--and the town itself--from destruction.
