An Entertainment Weekly Summer Reads pick and New York Times bestseller!

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. But she knows that 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 the fate of the world lies not in the machinations of the Martial court, but in stopping the Nightbringer. But in 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. But 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.
