In Temperance City, the streets are ruled by spelled-up gangsters, whose magic turf wars serve as a constant backdrop to civilian life. With magic strictly regulated, Eli Coello—whip-smart jewelry salesman by day, sultry torch singer by night—has always found it advantageous to hide his magical affinity for ink. All that goes up in smoke the day Eli is forced to use his magic to foil a jewelry heist, and in doing so unwittingly catches the eye of Duke Haven, leader of the fire-flinging Pyre gang. Seeing a useful asset, Duke promptly blackmails Eli into providing unregistered spellwork. Duke needs Eli's ink-magic to help him pull a dangerous con against a rival gang. As the heist comes together, Eli finds himself drawn deeper and deeper into the Temperance underworld—and, perhaps most dangerously, to Duke himself.
