War has shaped every aspect of Irena Soldan's life—her childhood, her work, her DNA. Unaware she is the genetic host of the second Seal of the Apocalypse, Irena battles for those who cannot fight for themselves as a top human–rights operative for The Omega Consortium, whose charismatic, publicity–loving boss holds a deadly personal agenda.

Chago has always been the quiet one among his warrior Scion brethren—the brooding, combat expert with a hidden soft side. A member of Divinity's covert special forces, he's protected humanity for more than a millennium and now his goal is retirement. In exchange for his freedom, Chago agrees to protect Irena against his ancient enemy as his final mission. Expecting a cauldron of female whoop–ass, he instead discovers a harbinger of peace amidst a world of ever–increasing violence.

Despite the cataclysmic circumstances, an undeniable attraction ignites between Chago and Irena. Together, they must unravel the ancient puzzle of the Seals and discover a way to defeat an unstoppable evil before they both become casualties of War.
