A millennium ago, mages made a bargain with demons, according to which they were required to leave the world of mortals. But the war is not over: the term of the agreement is expiring, and Hell once again threatens to break loose.
Vianna was bitten by a sylphid. As a result, the girl lost her magical power. To heal from the demonic fever, she had to leave her home and Ezra—the one she loved deeply.
Soon, fate brings her back to France, which is on the verge of collapsing under the onslaught of unclean spirits. Vianna is determined to recover the magic she lost and Ezra—now the Great Magus of Magi.
But before that, she must persuade him to negotiate with the enemy.
Only that Ezra has entirely different plans, and Vianna is no longer part of them. She must find out what he has in mind before the heavens ignite and the whole world is drowned in blood.
