When Nouf ash-Shrawi, the sixteen-year-old daughter of a wealthy Saudi dynasty, disappears from her home in Jeddah just days before her arranged marriage, desert guide Nayir is asked to bring her home. But when her battered body is found, Nayir feels compelled to uncover the disturbing truth, travelling away from the endless desert to the vast city of Jeddah, where, most troubling of all, Nayir finds himself having to work closely with Katya Hijazi, a forensic scientist. The further into the investigation he goes, the more Nayir finds himself questioning his loyalties: to his friends, faith and culture.
