The Shifter Hunter by Lacey Carter Andersen

How can someone so stupid unleash so much trouble on the world?

One mistake released spirits of chaos. Now, humans and supernaturals alike are getting into trouble all over our little town. But not to worry, our “old lady crew” is out of retirement.
And we know how to get things done.
Unfortunately for my best friend and I, we have more to deal with than a sudden outburst of fighting between the shifters. Yeah, if we can’t calm that down, we’re going to have an all-out war on our hands.
But what’s worse than that, one of our own has betrayed us. We need out who it was, and soon, or even if we can stop the shifters, there won’t be much of a world to save.
