Descendants of a mighty god clash against one another for their right to rule their father's land. As an ancient artifact surfaces from hiding, two brothers send their armies over frozen battlefields to prove their dominance. Matticus, the king of Hostellus, expands his campaign for the Sword of Kings and exhausts every resource to find it. Zededia, the Black Prince, slithers from the protection of his fortress to challenge Matticus and thwart his plans at every chance he finds.

A third brother stands between them, unsure of which side to favor. Prince Lucien, the youngest son of the late King Matias, struggles to find his place in the world. Both of his siblings reach to him for support, but in the end, he can only choose one side to stand on. Centuries of peace between the neighboring kingdoms rests on a razor's edge as the Sons of Osiris grow closer to reclaiming his power.

War, espionage, and the heroic acts of valiant men and women fill the pages of this saga. Enter the world of Osiria and witness the supremacy of the Sons of Osiris.
