A girl with a dangerous power.

A warrior they call the shadow of death.

A world divided and slowly dying.

Six-year-old Theodora grew up at the House, a place for girls born without power. Abandoned as a baby, she has no memory of her past beyond the melody that invades her dreams. So when an ancient presence starts whispering in her ear, she answers. 

The reward is fire; the price is the destruction of the only life she has ever known. Yet from the loss comes a chance at a better future… if she can learn to control a power that no one seems to understand. 

Across the ocean, Death's Arm warrior Kai struggles with the changes forcing him out of the shadows. With the neglect of those in power breeding dissent, he is called to do his job as their occasional assassin: cut it at the root. 

But when a strange restlessness makes him question an order for the first time... he finds himself on the path he never wanted, but can no longer avoid. After all, he may be the only one capable of stopping what is coming—a war where death is just the beginning.
