When ancient gods threaten to tear Chicago apart, one family's sacrifice may be the only thing standing between the city and total destruction.

Sofia Vega thought being a magical investigator for La Luna was complicated enough. But when corrupted energy starts spreading through the city's power grid, she discovers an even greater threat. Powerful deities are using her cousin Adriana's previous acts to break through into the mortal realm, transforming Chicago's infrastructure into a gateway for their return.

As blackouts plague the city and mysterious entities manifest in the darkness, Sofia must work with her estranged cousin to stop the rising tide of magical corruption. With help from a skeptical detective, a technomancer gifted in hacking both mundane and magical systems, and a Celtic goddess with her own agenda, they race against time to close the breach between worlds.

But victory may demand the ultimate price—one that could cost Sofia's family everything they hold dear.

Blending Aztec mythology, Celtic legend, and modern technology, The Old Ones is a pulse-pounding urban fantasy that will keep you spellbound until the very last page. Perfect for fans of Jim Butcher's Dresden Files and Ilona Andrews' Kate Daniels series, this thrilling tale weaves together magic, family, and redemption in a uniquely Chicago setting.

Join Sofia Vega as she faces down ancient gods, confronts family betrayal, and discovers that sometimes the hardest battles aren't fought with magic, but with the heart.
