Art student and monster's apprentice Karou finally has the answers she has always sought. She knows who she is - and what she is.

But with this knowledge comes another truth she would give anything to undo: she loved the enemy and he betrayed her, and a world suffered for it.

While Karou and her allies build a monstrous army in a land of dust and starlight, Akiva wages a different sort of battle: a battle for redemption. For hope. But can any hope be salvaged from the ashes of their broken dream

Karou and Akiva find themselves on opposing sides as an age-old war stirs back to life, in the stunning sequel to Daughter of Smoke and Bone.
