Deandra

"She will clothe herself in a dead girl's body to fight you. Beware the coming of the Remnant." — Aliester Crowley

Since before the beginning of time she has traveled alone—a remnant of another universe—the last of her kind.

Now she is living as Deandra Duke—adopted daughter of demonologist Mark Duke—living in a borrowed body. Together, they must stop the evil Roger Thornehill in his attempt to claim the blackest of black books—The Compendium Infernal—a grimoire that will give him control of the demonic hordes of hell.

But even as Mark struggles to control his personal demons while training Deandra to be not just a weapon but a human being, Thornehill has found his own inhuman assistant—Suthuria—the queen of hell.

Evildoers will learn the hard way that when you need to fight fire with fire, Deandra is that fire.
