The Harbinger - Terra Invictus, #2

The Harbinger, the sequel to Terra Invictus, follows two warriors fighting on opposite sides of the Ice Wall as the worlds they know begin to fracture. In the shattered remains of America, Jack Arthur Wallace leaves the fragile sanctuary of Fort Libertas and leads his knights into a lawless wasteland in search of a man who may hold the truth behind the nation's collapse—and the secret war that has haunted Jack's family for decades. Beyond the Wall, Legatus Valentia Scipio commands the defense of an ancient Atlantean fortress as a legendary enemy returns at the head of an army of giants, monsters, and forgotten powers. As hidden conspiracies emerge and once-unbreakable alliances begin to fail, Jack and Valentia are drawn deeper into conflicts far greater than either of them imagined. Their separate struggles become battles for family, faith, honor, and the survival of civilizations on both sides of the world. And while humanity fights to endure the darkness already upon it, an ancient warning draws closer, heralding a war that could decide the fate of all Terra.
