Darkness Splintered (Dark Angels #6)
When Risa loses the second key to hell, she angers several powerful people, and she’s starting to feel the pressure from all sides. She gets a visit from her father, who gives her an ultimatum: Get back the key or he will kill her friends.
Risa 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, Madeline Hunter, 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 second gate is opened and brings the world closer to all hell breaking loose...
