The Eastern Isles, an empire of humans, beastkind, and Fae, have recovered from a divisive war caused by an infectious entity. Humans established the Commission as a defense mechanism; however, mistrust of the Fae races has only increased while upholding their duty to protect against dangers.

Beast, Kovuco Blackstar, born of a deviant legend, lives in the shadow of remorse until he meets the enchanting Lady Ameilja Rose Frost, a human seer of the Eastern Isles. Kovuco is unique among his kind, but even more troubling, he harbors an illicit attraction toward Ameilja, whom he's strictly employed to protect.

Ameilja isn't your typical noblewoman; she's an advocate gifted with an unfathomable power, a power that makes her a prominent tool in the Commission's goal. Unknown to Ameilja, her rare ability is also a fatal instrument in an even darker plot that threatens the fabric of all life.

While dealing with internal struggles, Kovuco finds himself increasingly drawn to his lady, until they're both compelled to do something that will irrevocably bind their destinies. The fateful event between Kovuco and Ameilja may be the only hope for eradicating an ancient evil that's risen against the world, all while harboring the most significant obstacle: humans don't give their hearts to beasts.
