Bloodlust. Power. Vengeance. War is coming. And all must be ready. The drums of war are beating, their echoes filling Dorcha Wood as Fiadh, and those who stand with her, ready themselves for what is coming. Beyond the forest's borders, Aos Sí armies march, exacting a terrible vengeance on mankind as they fulfill the dark wishes of Rygeil—a ruler who has forsaken the Great Mother, Danu. But, vanquishing the children of men will take more than the magic flowing through Aos Sí veins. Rygeil covets Fiadh, believing she is the key to unlocking a power so vast none could stand against him. As destruction sweeps across the landscape, armies of men are amassing, flocking to a corrupt ruler who seeks more than the defeat of the elven army. Like Rygeil, Lord Darragh hunts Fiadh. Her power. Her blood. His dark purpose, twisted by the malevolence of an evil woman. And, at his side stands Gideon, a man who vowed to see his people avenged whatever the cost. Erabel is under siege. All that stands between its downfall or salvation is one young woman whose blood sings with the power of the earth itself.
