Cursed Hunter by Lacey Carter Andersen

An ex-demon-hunter. Three possessive demons. And a Rebellion against impossible odds…
Sharen doesn’t know what the hell she is. Except that she’s not human. With her demons at her side, she’s determined to discover the truth of her parentage.
But things aren’t that simple.
The angels are searching for her. The Hunters are trying to kill her. But rather than hiding out quietly, she’s decided to do the impossible: save as many innocent demons as she can.
Even though putting her in danger goes against every one of her protective demons’ instincts, they’ll help her in her mission. Because they love her. And, because they know they can’t stop her.
Yet, not everything is as it seems. The shadows hold secrets. And these kinds of secrets? Well, they’re the kind that just might get them killed.
