The story follows the three —Grey, Vivi, and Iris—who famously disappeared from an Edinburgh street as children, only to reappear a month later with no memory of where they had been. Upon their return, they were physically changed: their eyes had turned black, their hair white, and they possessed a magnetic, almost dangerous beauty that compels others to do their bidding.
Ten years later, the eldest sister, Grey, goes missing again under suspicious circumstances. Iris and Vivi must follow a trail of bizarre clues—including a corpse falling from a ceiling and a man in a horned mask—to find her and finally uncover the truth about their past.
