Fifteen-year-old Scarlett Adams is caught in a media storm after her strange disappearance – which she refuses to explain. Far away in Peru, Matt Freeman guesses the truth. Finally, he has found the fifth Gatekeeper: the last of the Five who must stand together against the dark power of the Old Ones. But he’s not the only one looking for her. Evil is one step ahead, luring Scarlett to Hong Kong, and trapping her in a dying city where there can be no escape.
