Vengeance of a Queen by Elizabeth Brown

After turning a demon inside out on the battlefield, I learn that I’m a new breed of queen. Like my best friend, Ayla, I’m the perfect combination of shifter and witch. I just have no idea how to use my new powers. My panther isn’t the same either. There’s a lot to adjust to, but I don’t have any time to think about adjusting.
Ayla, Caleb, Malcolm, and I have gone off to Ireland in search of answers. Answers about the prophecy, about the mysterious force that saved Malick during that final battle, about how Kelly, Darcy, and I are suddenly queens like Ayla and her sisters, but most importantly, about Ayla’s sisters and where they’re hidden.
I’ve got so much on my plate that you would think the last thing I want to deal with is a temperamental mate, and you’d be right. I knew the instant I changed on the battlefield that Malcolm is my mate. He’s claiming that he’s giving me time because of all the changes that I’ve gone through lately, but I think that’s a load of crap. I’m determined to make him see that I don’t need time when it comes to claiming him.
He does have a small point, though. There are so many different puzzle pieces that we have no idea how they all connect. We’re going to need to put those pieces together quickly if we want to survive. Malick is back, but he isn’t alone. And Malick turns out not to be the threat we originally thought he was. The goddesses had told Ayla that there was someone out there worse than he is, and they weren’t kidding. What we learn about those seven beings is terrifying.

If all the gods and goddesses couldn’t kill them, how the hell are we supposed to?
