Badge & Flame: A Chicago Undeground Story

A gripping urban fantasy thriller where magic meets law enforcement in Chicago's dangerous streets

Detective Sofia Vega walks between two worlds—sworn officer of the Chicago PD and secret agent of La Luna, the city's magical governance. When firefighters start dying from impossible "cold fire" that burns from the inside out, Sofia must use both her badge and her fire magic to hunt a killer harvesting power from those with latent magical abilities.

As the body count rises, Sofia discovers a terrifying pattern: the murders mirror an ancient ritual that once triggered the Great Chicago Fire. With each death, former firefighter Marcus Brennan grows stronger, building toward a catastrophic magical working that could devastate the city.

Partnered with skeptical Lieutenant Jack James, Sofia races to identify the next victims while navigating department politics and magical protocols that weren't designed for the modern world of body cameras and social media. When Brennan targets firefighter Jason Rivera, Sofia must risk exposing her magical abilities to save him—and potentially shatter the veil between worlds.

With time running out, Sofia faces an impossible choice: follow La Luna's rules and watch Chicago burn, or embrace forbidden family magic that could save the city but cost her everything she's worked for.

Badge and Flame is the explosive fourth novel in the Chicago Underground series, perfect for fans of Jim Butcher's Dresden Files, Patricia Briggs' Mercy Thompson series, and Ilona Andrews' Kate Daniels books.
