Morgavia Sanctus is being hunted. She doesn't remember who or why. Something terrible happened to her, some kind of nightmarish event that left a mark in the form of “red dreams” and physical agony that could fall on her at any moment. Morgravia's life is under threat, her memories are fragmentary, and she arrives in the underhive of Blackgeist to get rid of her pursuers and find the Broker, a merchant of memories and a master of psychic manipulation. However, a plague soon hits the city, turning its inhabitants into bloodthirsty monsters. Order has been disrupted and death and massacres have become the norm. Finding herself drawn into a bloodbath, Morgravia must flee again. But while evil eaters prowl the streets, is there any hope of stopping this infection?
