Hellsbane Hereafter by Paige Cuccaro
The war between good and evil is on and Emma Jane is caught in the middle. Both sides want her working for them and both sides know how to make her suffer if she chooses wrong. But someone has raised the stakes, using innocent humans as pawns, and Emma Jane isn't sure who to blame. Discovering the truth will be hard enough, but what she used to believe about right and wrong, good and evil--what she used to believe about herself--is changing. And something tells her whatever happens, nothing is going to be the same again.
Being heaven's bounty hunter isn't easy...Emma Jane Hellsbane just makes it look that way.
