Aidan Montgomery dreams of fire. He fears the fire growing within him, the power taking over and killing everyone he knows and loves. After spending months hiding in the Waste, he heads south to meet up with the girls only to find them deployed to the war effort in Rebluinia. Struggling to cope with a terrible tragedy, he doesn't know if he can control the fire within. He doesn't know if he is safe to be around.

Nadia Oswald is a pacifist. Yet she finds herself fighting again and again, against the military, against her father, against everything working to constrain her and her power. She is terribly afraid of her power being turned toward violence and death. Even with Elise Chulyin by her side, how can she hope to fight every person who seeks to control her?

From all sides enemies rise. Ecrium's war rages on, drawing Aidan and Nadia into the fray. Anchor witches and elementals rise to power, fighting for Ecrium and seeking to conquer Rebluinia and the rest of the Falgar. But Ecrium is the least of their worries. In Egraria witches are dying, murdered for their power. The killer wants anchor power and won't stop until he has it. Even if that means killing every last one.

In this sequel to Hope & Fire, follow Aidan and Nadia as they face their greatest challenges yet. With Ecrium on the rise and the killer tracking their every move, can they stand together and bring their world back to peace? Or will their fears come to fruition as all they know and love falls apart?
