Beyond the Martial Empire and within it, the threat of war looms ever larger. Helene Aquilla, the Blood Shrike, is desperate to protect her sister's life and the lives of everyone in the Empire. Yet danger lurks on all sides.

Emperor Marcus, haunted by his past, grows increasingly unstable and violent, while Keris Veturia, the ruthless Commandant, capitalizes on the Emperor's volatility to grow her own power—regardless of the carnage she leaves in her path.

Far to the east, Laia of Serra knows that the fate of the world lies not in the machinations of the Martial court, but in stopping the Nightbringer. During the hunt to bring him down, Laia faces unexpected threats from those she hoped would help her, and is drawn into a battle she never thought she'd have to fight.

And in the land between the living and the dead, Elias Veturius has given up his freedom to serve as Soul Catcher. However, in doing so, he has vowed himself to an ancient power that demands his complete surrender—even if that means abandoning the woman he loves.

The circle is closing. The stakes are high. And old truths will live again...

The Emperor has been murdered, leaving the Annurian Empire in turmoil. Now his progeny must bury their grief and prepare to unmask a conspiracy.

His son Valyn, training for the empire’s deadliest fighting force, hears the news an ocean away. He expected a challenge, but after several ‘accidents’ and a dying soldier’s warning, he realizes his life is also in danger. Yet before Valyn can take action, he must survive the mercenaries’ brutal final initiation.

Meanwhile, the Emperor’s daughter, Minister Adare, hunts her father’s murderer in the capital itself. Court politics can be fatal, but she needs justice. And Kaden, heir to an empire, studies in a remote monastery. Here, the Blank God’s disciples teach their harsh ways – which Kaden must master to unlock their ancient powers. When an imperial delegation arrives, he’s learnt enough to perceive evil intent. But will this keep him alive, as long-hidden powers make their move?
