Every supernatural race is at war. Enemies rarely see eye to eye, and yet a human and a banshee find themselves working on the same side as an unexpected war rages around them. Bianca is a newly appointed hunter with a lack of training who must learn to perform patrols, bear the weight of leadership, and navigate the shadow world alone. Morana is a tortured member of a scarce race who hears deaths call for every soul consumed by war, an unwanted distraction as she deals with her own broken heart. Together the girls strive to prevent further bloodshed as a new enemy approaches from the horizon, more chaotic and terrifying than anything the races have experienced before.
