Fallen Dark. Lost Guardians, #1

Anna has settled into her new life...as much as anyone can. She has few people to confide in other than her friends. And, of course, Victor Prince. When he disappears, they instantly suspect the involvement of rogue Guardian Erica Turner. It's her turn to rescue him, and this does not help the tension in their relationship. Now they have to stop Erica without hurting her or, worse, killing her, which will only create a monster.
Politics swirl around the story with the bad guys seeking power. On top of that, there's a witch hunter in town, and he is not good at distinguishing good magic from bad magic. To him, it is all straight from Hell.
