Damnation Marked (Descent #4)

There's something in the earth deep below Elise Kavanagh's territory. A shadow is falling upon local demons to devour their flesh and harvest their souls. And it's coming for Elise next.

The Union has an easy way out. They want to send Elise into hiding again with her former partner, James Faulkner. All she has to do is surrender the territory and trust that they can protect the ethereal ruins, the dark gate, and the city she's come to know as home.

Greater powers have other plans for Elise and her fabled power as Godslayer--plans that mean surrendering her life and blood to the most powerful demon alive. But if she descends, there's no turning back. Once she gazes into the abyss, it will gaze back into her... and Elise will be damned forever.
