Inferno

Olivia’s once-shining light now blazes with the fury of an avenging angel, leaving ruin in her wake. Gone are the days of soft hearts; endless compassion doesn't win wars with Hell.

Without an anchor (you mean Olivia, right? So maybe Without the anchor of Olivia's heart (??)), the jinni side of Holden grows stronger every day. Giving into his true nature might mean losing the one thing worth living for, but it's the only way to stop the rise of a darkness even the angel cannot defeat.

Every decision they make to re-establish balance in their world causes ripples through the universe, changing paths and intentions of even the most stalwart of friends. All it took was a single death to make waves through the Abyss. Now the lives of five people have been changed forever. No one will make it through unscathed.
