For years, Heather Tradescant had dreamed of the journey she and her father would take to England--a pilgrimage to the great gardens of history. Now that her father is dead, Heather is determined to fulfill his dreams. Unfortunately, her request to see the fabled 17th-century garden of Troytan House is denied by the owner. Though unwelcome, she braves the walls of briars and reaches the Victorian manor house beyond. She senses a strange mission of evil lurking, tainting the manor's peaceful beauty. Only then does Heather begin to wonder whether it is only stories of long-vanished witchcraft that haunt Troytan House or whether there is some more modern horror, nearer at hand, and far, far more dangerous.
