Two empires on the brink of annihilation. A crown bought with blood. A sacrifice that could destroy a soul.
Hailed as Caesar on a blood-soaked battlefield, the immortal Blessed Champion Galerius Manlius Britannicus never wanted to rule. But with Rome fracturing under the greed of rival tyrants and the fanatical magic of the Kerberos Order, he must lead his exhausted legions toward the capital. Galerius dreams of forging a just and honorable Republic from the ashes of a broken world. But as ruthless warlords circle and the grueling, magical siege for Rome begins, Galerius is forced to confront a terrifying question: to win the civil war, must he become the very monster he swore to destroy?
Yet the battle for the throne is a mere distraction. From beyond the dimensional Veil, an ancient enemy has returned. A resurrected Carthaginian armada has amassed in the shadows, wielding reality-bending magic and built for apocalyptic conquest.
To save Galerius and the world he fights for, the elite Lupan spy Keir volunteers for a suicide mission of the mind. She undergoes a harrowing ritual to absorb the soul of the captive Carthaginian Empress, Marwa, infiltrating the alien fleet as their returning goddess-queen. But the mind of a world-conquering tyrant is a dangerous place to hide. Surrounded by zealous assassins and suspicious generals, Keir must wage a desperate, silent war against Marwa's crushing, centuries-old ego.
As the bloodbath for Rome reaches its crescendo and the Carthaginian war machine prepares to strike, two lovers fight impossible battles worlds apart. Can Galerius seize the Empire without sacrificing his humanity? And can Keir dismantle an armada from the inside, or will the Empress within consume her entirely?
