Istanbul beckons Celeste Hamilton like a siren. Entranced by the misty city of mosques, bazaars, and palaces, her dream adventure in this city, split by the sparkling blue sea, soon turns into a nightmare. A web of deceit pulls Celeste from bright, sunlit streets into shady back alleys along the ancient Bosphorus. Without understanding, she's stumbled onto a villainous secret. Her landlady lets slip puzzling comments that don't make sense. The sinister charms and dark magic spells she places in Celeste's room are horrifying. Then, the morose caretaker of the orphanage where Celeste volunteers starts staring at Celeste's beloved boys like a vulture sizing up its next meal. When Celeste's favourite boy goes missing, Celeste discovers that she herself is the target of a dark plot. Can Celeste save the child - and herself - before someone destroys her?
