The Devil Inside (Book II in the Dark World Trilogy)

Some evil is born—others are made.
With the Queen presumed dead and a new world on the horizon, the residents of Dark World must now face an uncertain future. Unless all the six scrolls are found and used to reignite the Crystal Pyramid, all the creatures of Dark World will die.
Despite newfound love and happiness, Fate’s hunger for souls soon becomes uncontrollable. With no other option, she surrenders to a cure with unknown consequences—only to face an even greater nightmare.
As the mystery behind Ever’s condition deepens, Kane is forced to consider what lies beneath—a beauty or a beast.
And whether or not to slay the monster before it wakes.
