Wicked Oath - Jenna Wolfhart

Things have gotten a little complicated. Asmodeus and I thought we could win the game, but we were wrong. It's only just beginning.
Determined to keep us apart, Lucifer drags me into a world of flames. There's only one way out. I have to sign a demon contract. Again.
But the terms of the deal are far worse than I could have ever imagined. Lucifer offers the unthinkable. He'll end the brutal game for souls and spare the world from eternal torment.
On one condition.
I must rip out Az's heart.
This is the final book in the Demons After Dark: Covenant trilogy.
