A revenge-driven pyromancer fights to save her greatest enemy's stronghold—and their world—from annihilation in the third book of this epic fantasy series.

As remorseless as she is brutal, Tallah Amni commands her fate with an iron grip as she seeks revenge against the immortal empress who murdered her sister. But the goddess Panacea denies her and her allies safety when they transport themselves to Edana's most dangerous battlefield: twin fortresses called the Rock and the Anvil. Now, they must defend this battleground, as these towers are the only defense against the daemon-infested Cauldron below—and the only barrier against otherworldly invasions.

Under the threat of overwhelming monstrous hordes, both strongholds are about to fall. Their loss would be a death blow to Empress Catharina's empire, but Tallah refuses to let valiant warriors perish for the sake of her own vengeance. Using ancient arts learned in Grefe and the absorbed souls of enemy mages, she risks her powers to devastate the relentless army of mutations, even as her healer friend, Sil, breaks away from the secretive teachings of the School of Healing and the Other, Vergil, begins to peek through the heavy curtain of amnesia that's plagued him for so long.

However, Tallah suspects something far worse is behind this invasion when a formidable dragon strikes and an especially malicious daemon reveals its immense strength. Seeking out the puppet master behind these latest attacks, she embarks on a dangerous solo mission that takes her into the Cauldron's hellish depths. But uncovering the truth means losing control of not only her will but the always-contentious souls residing within her. And when rescue reveals a treacherous agenda, Tallah will face a bitter choice between evil victory and soul-destroying defeat . . .
