These Dangerous Fates by Whitney L. Spradling

I live in a magical world. A world filled with vampires, shifters, and mages.
Mysteriously, I was born without powers.
After living the past two years in a personal hell, enduring abuse from a fiance I didn’t choose, I finally snapped. An act of self-defense against my fiance angers my father, and in retaliation for my actions, he creates the ultimate contest. One that only the most powerful magicals can compete in to win my hand in marriage.

It sounds bleak, but anything has to be better than my current situation. At least, I thought so, until they appeared in the middle of the night to whisk me away.

A vampire prince.
A wolf without a pack.
A powerful mage.

My three captors do everything they can to win the contest, and as the attraction between the four of us grows, so does their desire to keep me safe.
