Trial by Fire — April M. Reign

In an attempt to balance her father's unruly attitude “downstairs,” Dhellia steps forward to represent a soul at his trial by fire against Lucifer and his demons -- a decision she trained long and hard to attempt on her own. But as good and evil get closer to a global confrontation, Dhellia owns her powers, hones her skills and puts herself in harm's way in order to save those in the line of fire. What she discovers is that life isn't always fair and some will stop at nothing to see her fail. Dhellia is a funny, fresh and sassy, fast-paced series about a young woman whose birthright is princess of the underworld -- she's mad as Hell about it, and is determined to use her powers to beat her father at his own game!
