In the frozen kingdom of Saiduan, invaders from another realm are decimating whole cities, leaving behind nothing but ash and ruin. As the dark star of the cataclysm rises, an illegitimate ruler is tasked with holding together a country fractured by civil war, a precocious young fighter is asked to betray his family and a half-Dhai general must choose between the eradication of her father’s people or loyalty to her alien Empress. Through tense alliances and devastating betrayal, the Dhai and their allies attempt to hold against a seemingly unstoppable force as enemy nations prepare for a coming together of worlds as old as the universe itself. In the end, one world will rise – and many will perish.
