Emilia Wilde has seen her share of calamity, mystery, and intrigue. As a private investigator in the Victorian city of Etherbury, she can't shy away from the seedy and foggy underbelly of her town. However, when a seemingly normal case ends up being connected to her family, she is drawn into a part of her city that she has never seen before. Apocryphal cults, mad science, and dark alchemy stand in her way as she races towards the center of a case that forces her to look at her own past, and a tragedy she refuses to address. With the help of her best friend Aisling, a strong airship captain, and her dragon companion Evaki, Emilia attempts to unravel a plot that spans countries and continents, and has been killing the poor and forgotten citizens of Etherbury.
