The Magician's Ruins

She's the hope of the world… or its destruction.
The portals to the underworld are unguarded, and demons roam free in the Southwest. To return the world to balance Echo Maria Ruiz must survive enough trials to meet with the Magician in his ruined city and learn the secrets he holds. Secrets like the location of her best friend.
Alone and unprepared, Echo must trust Honani, her spirit guardian, and Zeke, the handsome, mysterious warrior who battles demons and monsters at her side. In her darkest moments in the Magician’s ruins, Echo discovers betrayal lurks, and her warrior may not be her hero after all.
