Young Jane Silverlake lives with her father in a crumbling family estate on the edge of Hampstead Heath. Jane has a secret—an unexplainable gift that allows her to see the souls of man-made objects—and this talent isolates her from the outside world. Her greatest joy is wandering the wild heath with her neighbors, Madeline and Nathan.
But as the friends come of age, their idyll is shattered by the feelings both girls develop for Nathan, and by Nathan’s interest in a cult led by Ariston Day, a charismatic mystic popular with London’s elite. Day encourages his followers to explore dream manipulation with the goal of discovering a strange hidden world, a place he calls the Empyrean.
A year later, Nathan has vanished, and the famed Inspector Vidocq arrives in London to untangle the events that led up to Nathan’s disappearance. As a sinister truth emerges, Jane realizes she must discover the origins of her talent, and use it to find Nathan herself, before it’s too late.
