Fangs & Freaks by Cassie Lein

Years ago, they betrayed her, bound her in flames, and left for dead. They thought they killed her, but they did something far more than that, they made her immortal.

Now, as the legend goes, whisper her name into a mirror three times, and she’lI will rise again — a spirit bound to vengeance, a deadly beauty with fire in her heart.
When Bellonna is summoned by a desperate shifter, she revels in the thrill of seeking justice.
Until someone intervenes, undermining her mission and rendering her unneeded. What was once a job quickly becomes personal.
The Crimson Brotherhood have no idea what they’ve brought into their club. A dangerous game of cat and mouse begins. Who will emerge victorious—or will they all go up in flames?

But as passion and fate collide, Bellonna must decide whether to fulfill her deadly duty or risk everything to protect the souls who may be her salvation.
