Blood Redemption (Angel's Edge #3) by Vicki Keire

Trapped in the Dark Realms, Caspia finds herself the unwitting leader of a growing Nephilim rebellion. Plagued by strange dreams and intrigue, she learns to master her Azalene abilities when all she wants is to find her way back home.

To Whitfield. To Ethan.

When they meet in the Dreamtime, Caspia can tell something is wrong. Whitfield seems increasingly militarized. Ethan is agitated; Asheroth makes less sense than ever; and the Blackwood witches are teaching Logan deadly gifts. Most disturbing of all is Belial, who is as charismatic as he is cruel.

But Belial isn’t the only one threatening Whitfield. To avoid another Nephilim war, the Realms of Light decide to attack their ancient enemy first. Caspia, her hometown, and everyone she loves happens to be in the way. With the Light poised to strike from one side, and the Dark Realms on the other, she and Ethan must fight their way back to each other and try to protect the life they’ve built.
