Opal Yong-ae is a freelance Cleaner in the DFZ—the Detroit Free Zone, a lawless city where buildings move on their own, gods walk the streets, and dragons cause traffic jams. Saddled with magical debt to a dangerous creditor, she empties abandoned apartments and resells what she finds to survive. When her latest job turns up a murdered mage hiding something enormously valuable, Opal must decide whether the payout is worth the danger—and in the DFZ, the danger is always lethal.

Opal is broke, snarky, and sharper than anyone gives her credit for—a mage who turned an art history degree into a survival skill and refuses to be a victim even when everything is stacked against her. She leads with wit and improvisation, forming unlikely alliances and discovering that her underestimated power might be exactly what the DFZ needs.

Across three books, Opal navigates the chaotic, capitalism-soaked underworld of the DFZ alongside Nik, a security contractor with his own complications, as small-time jobs spiral into city-shaking conspiracies. The series builds a vivid portrait of a sentient city that is itself a living character, celebrating urban fantasy capacity for humor, heart, and breakneck pacing. By the finale, Opal has moved from scraping by to becoming a genuine force in a world that wanted to chew her up.
