In a city split into two opposing sides, power comes in many forms: bloodlines, money, love, and—most importantly—secrets. An heiress in the most notorious family in Lynchaven, Camilla Marchese is doing all she can to keep her family’s syndicate, the Iron Saint Railway, from slipping into bankruptcy. When the gorgeous and depraved Nicolai Attano, the leader of a rival family, offers to pay off the Inspector in exchange for her hand, she has no choice but to give up not only her throne—but her name. Nico has his own motivations for their union beyond maintaining peace with her family. A serial kidnapper known as The Collector has been ravaging the streets of Remnant Row, stirring up mistrust between natives and descendants. If Milla can help restore safety to his streets, he’ll have no need for her or her family’s company. Find the Collector, prevent a war between their sides of the city, and pay off the family debt before she turns twenty-one. If Milla can fulfill her end of the bargain, she’ll walk away with more freedom than she’s ever had before. But this deal plunges Milla into the city’s dark underbelly where remnant magic and arcane science compete in a deadly game of depravity. When forbidden feelings rise for her new husband and dark family secrets come to light, Milla must discover the truth about her past before it gets them both killed or worse—collected.
