Perfect Storms by Elle Middaugh

Alexis Ravenel: Vengeful. Virtuous. Victorious Queen?
The Storm King is the ultimate evil.
He’s abused and tortured innocent citizens. He’s murdered people my princes and I love and care about. And he’s about to get what’s coming to him.
But first, we must save Blackwood Kingdom from international war. Fae, sirens, and harpies are coming to destroy us, and short of a divine intervention, I’m not sure how we’re going to survive it. Our only hope is amassing enough allies to give us a fighting chance.
If we can somehow pull a miracle out of thin air, and actually live long enough to face the wicked king, then I swear I will fulfill the destiny granted to me the moment I received my powers…
I will kill the king, even if it’s the last thing I ever do.
