Shadowalker

Ediline is the Shadowalker. As she adjusts to her new power, she must lead a rebellion against the newly proclaimed Lord Empress Tathia, banding together disparate allies with their own slanted motives. Yet Ediline knows that the even greater enemy lies in the darkness behind the Empress, somewhere Ediline is terrified to reach into.
When she accidentally stumbles into the barren realm of Nowhere, she discovers an ancient secret, a slumbering cosmic power, a lost soul, and the horrible Fantasma, hellbent on tearing into her world. The struggles she faces with her alliance against the Empress-and the looming confrontation with these ancient evils-threaten to overwhelm her, and they are disastrously intertwined.
To defeat her world's oldest enemy, she fears she will have to give in to the power that she has been Granted-losing herself in the process. In this epic conclusion to her story, Ediline's fate is yet to be decided, and everyone who cares for her will fight until the end alongside her to ensure that, after the darkness is put down, she can see another sunrise.
