After a decade disguised as her missing twin brother, Kasia leads a gang running liquor for the most powerful mob in the city. The ruse gave her a foot in the door, but in order to keep her position-and more importantly, to keep money flowing in for her and her sick mother-she has to be willing to do whatever it takes. And what it takes is cold calculation and a ruthless hand. She needs both in spades when a new police chief is determined to eliminate Detroit's mafia, a threat to destroy everything she's built.

When Kasia learns Sophia-a glamorous flapper who owns an underground queer club-has an unusual hold on the supposedly-incorruptible chief, Kasia wants in on Sophia's secret. Blackmailing Chief Harding could protect her gang and give her a leg up in the mob's ranks. But her plan unravels when she falls for Sophia's fiery spirit and sophisticated charm. After years of avoiding relationships to protect her identity, her feelings for Sophia lead Kasia to take bigger risks than ever. Risks that endanger her gang, her secret, and her life.
