Helena Marr divorces people from curses, fae bargains and vows that refuse to die with them. Then the Devil walks into her office and asks her to end the oldest marriage in creation: Hell’s binding union with Heaven.

The Covenant has no exit clause. To find one, Helena must descend into Hell’s archives, uncover the truth behind Lucifer’s supposed fall, and recreate the contract’s intimate rites with a client whose self-control is far more dangerous than temptation.

Every clause exposes another lie. Every touch makes professional distance harder to defend. And when Helena finally discovers a way to free him, she learns the cost may be far greater than one damned soul or even Hell itself.

Some marriages destroy two lives. This divorce could tear apart creation.
