Magic burns - Ilona Andrews

Mercenary Kate Daniels tries to save her city from divine intervention in this novel in the #1 New York Times bestselling urban fantasy series.

As a mercenary who cleans up after magic gone wrong, Kate Daniels has seen her share of occupational hazards. Normally, waves of paranormal energy ebb and flow across Atlanta like a tide.

During a flare, gods and goddesses can manifest and battle for power. The stolen maps are only the opening gambit in an epic tug of war between two gods hoping for rebirth, and if Kate can't stop the cataclysmic showdown, Atlanta may not survive...
