Something is watching from the dark corners of her cell. Saffron has been imprisoned in Medlock’s Detention, where the guards are soulless, the prisoners are secretive, and the shadows seem to sharpen their claws. But she knows something even darker is lurking in the depths of the cells. Her friend Ray was sent here before he vanished without explanation. The only clues he left behind were frantic warnings about a creature called the caliginent — a monster that feeds on thoughts and devours sanity. As Saffron searches for answers through forbidden rooms, cult-like séances, and disturbing drug trials, the line between truth and delusion begins to blur. The shadows grow closer. Her thoughts become unreliable. And Saffron begins to fear the most dangerous thing in these cells might not be the monster everyone fears — but her own unraveling mind.
