Magic Time: Ghostlands (Magic Time Series, 3)

In an altered America where machines no longer work and magic holds sway, former lawyer-turned-visionary leader Cal Griffin guides his small band on a quest toward the Source of the Change -- following a trail he hopes will reunite him with his abducted sister, Christina, transformed into one of the powerful, enigmatic beings called "flares." Armed with little more than compassion and a determination to heal the world, Cal, the warrior Colleen Brooks, Russian physician Doc Lysenko, and bipolar street wizard Herman "Goldie" Goldman encounter old foes and new friends in a landscape of unimaginable beauties and magnificent horrors -- forced to confront the frightful secrets of an emissary from a dread region and to trust in a brilliant triumvirate of grad students who could get things running again ... at a terrible cost—as the final moves in humankind's ultimate nightmare are played out in the depths of the Ghostlands.
