Crown of Shadows (Coldfire Book 3)

For over a thousand years, humanity on Erna has been locked in a tense balance with the fae, a powerful force that feeds on the human mind. Now, a Iezu demon named Calesta has declared war, seeking to reshape mankind into beings whose only purpose is to satisfy his insatiable hunger for suffering.

Signs of his impending victory are emerging, and only Damien Vryce, a warrior-priest, and Gerald Tarrant, an undead sorcerer, stand in Calesta's path. To save humanity, they must utterly destroy the demon. However, the true nature of the Iezu remains a mystery, and no one has ever managed to kill one.

Faced with a potentially invincible enemy, Damien and Tarrant must risk everything. Their battle will take them on a perilous journey, with the fate of mankind hanging in the balance. The cost of failure is not just their lives, but the very soul of humanity.
