It is 1884, and Eliza searches for her childhood sweetheart, who vanished from the streets of Whitechapel. No one believed her when she said that he was stolen away by the fairies. Beneath London, the fae in the Onyx Court are under siege, the iron of the underground railway destroying their home of three centuries. Many flee to the countryside. Those who stay have one goal: to find safety in a city that does not welcome them. But what price will the mortals of London pay for that safety?
