Darkness Splintered

Description for DARKNESS SPLINTERED by Keri Arthur:

Risa has angered several powerful people, and she’s starting to feel the pressure from all sides. She also finds herself under the scrutiny of the vampire council, some of whom consider her a monster who should be destroyed. But they offer her a bloody bargain: Take on the lethal head of the council and others will support her.

As the search for the keys to hell heats up, Risa realizes that she has no choice. For the sake of the people she loves, she must find the keys -- and get rid of Hunter -- before the next gate is opened and brings the world closer to all hell breaking loose....
