A Court of Darkness by A.K. Koonce

The deadliest magic is always the prettiest.
And my magic, it’s to die for. Literally.

As the notorious rejected princess of the Kingdom of Fallen, it’s no surprise I’m sneaking around the castle I was exiled from over a year ago. It’s not shocking I’m fist fighting with the wildest men of the wild hunt. It’s definitely not astonishing I’ve come to find myself locked in my father’s dungeon because of it all. I only wish I hadn’t brought the psychotic men of the wild hunt with me.
I can find out the Mad King’s secrets. I can stop his destruction myself. He is my father after all. His reckless magic runs through my blood.
And like I said, it’s to die for.
One of us will find that out first hand.
