After the disappearance of her journalist mother four years ago, Ash has solidified her place within the Syndicate, one of three governing factions in the famed city of Drenthe. Precisely where she needs to be if she has any chance of solving her mother's final investigation, the unsettling pattern of missing girls taken from the district Ash reluctantly calls home.
When the pattern begins anew, she follows her mother's last lead to a high-ranking member of the Syndicate, but her plans go awry when she is caught in a devastating trap, dragging Lina - an upper-class girl with blood on her hands and a stolen memory - into the crossfire.
Cast into the ranks of stolen girls, another part of the pattern she had endeavoured to unravel, Ash gains Lina's trust as they seek to learn the truth of the facility they have been brought to. But the intentions of their captors, those who speak of long-dead Saints with frightening conviction, are more sinister than they could've imagined.
Forced to fight against illusions of the past and the twisted reality of the city's history, Ash must save herself and the girls she has vowed to protect before she becomes another victim of a Saint she never believed in.
