Amy Leatheram has never felt the lure of the mysterious East, but when she travels to an ancient site deep in the Iraqi desert to nurse the wife of a celebrated archaeologist, events prove stranger than she could ever have imagined. Her patient’s bizarre visions and nervous terror seem unfounded, but as the oppressive tension in the air thickens, events come to a terrible climax–in murder.
