A Prince So Cruel

He needs my help, but he'll be my downfall.
A prince by morning.
A cretin by noon.
A beast by nightfall.
There is a curse on his blood, an ailment that, if revealed, could destroy his kingdom.
The only one who can help him is me, a human with average healing abilities. It's what the Envoy told him, and her word is law.
I'm his only hope.
He sends his blue-blooded friends to kidnap me so I can join their quest to Mount Ruin, the only place where I can heal him.
The path is terrifying, and the prince is lying, hiding things from me. To make matters worse, he isn't always nice. A Fae prince isn't supposed to lust for a human, especially when she's his prisoner. And a human girl isn't supposed to burn for someone so out of her league.
The quest might kill me, but it's my heart I'm worried about.
