"What is the most powerful force in the world?"

Beatrice Harrow was raised in seclusion, separated from the Read Kingdom and protected from the mysterious mechanisms of the other four races, but they are not as blind to her as she is to them. Even before she steps foot inside the Academy, they know her name and they know the truth about her birth. She is one of the Tainted: a mixed-breed creature with the blood of a monster, clinging to legitimacy by the genes of her human father. She is more beautiful, more powerful, and more despised than any other being in the Read Kingdom.
Her life was never going to be easy, but when fate throws her together with Cale, the troublemaking son of her father's sworn enemy, and Hazen, the intimidating crown prince of the Read Kingdom, she quickly discovers that her problems haven't even begun.
In a world built on status, there are lines that can never be crossed.
In a time of peace, it is inevitable that war will whisper on the wind once again.
In a land of mixed blood, a Tainted Creature can either be killed ... or they can be recruited.
