After getting out from under the Vatican's thumb, Ellyria's life is looking up for the first time in years. Between her budding romance with the demon Zangrunath and college, she has never been happier. However, tragedy looms in the near distant future as she is constantly reminded of her magical contract with the demon that would leave her alone at its inevitable conclusion.

When an unexpected twist of fate leaves Ellyria disfigured and in agony, they seek assistance from an unexpected ally who holds their fates wholly in his hands. The Prince of Darkness has no compunctions or obligations to assist them except for his own agenda. With a thought, he could crush them both, but, if they could somehow convince him otherwise, they'll owe the devil himself a debt of gratitude that has yet to be seen in all of history.

Earning a favor from Lucifer makes blackmail, politics, and misogyny look pathetic by comparison.
