In the New York Times-bestselling author's latest Arcane Society novel, a paranormal killer pushes an unlikely duo's powers and passions to the limit.Virginia Dean wakes at midnight beside a dead body, with a bloody knife in her hand and no memory of the evening's events. Dark energy, emanating from the mirrors lining the room, overpowers her senses. With no apparent way in or out, she is rescued by a man she has met only once before, but won't soon forget.Owen Sweetwater inherited his family's talent for hunting the psychical monsters who prey on London's women and children, and his investigation into the deaths of two glass-readers has led him here. The high-society types of the exclusive Arcane Society would consider Virginia an illusionist, a charlatan, even a criminal, but Owen knows better. Virginia's powers are real—and they just might be the key to solving this challenging case.
