In a kingdom dominated by wolves, the humans have risen to battle the oppression forced upon them by the beasts, and Avalon seeks no part in this feud. She and her ill father live isolated from the environment of war, seeking solace in a small cottage hidden deep within a valley on the outskirts unbeknownst to the wolves and humans. As her father's sickness worsens, she's forced to venture into a human territory for medicine. However, when a surprise attack launched by the beasts results in her being taken in as an alleged war prisoner, her ties to this political feud grow far greater than she could have ever hoped. She's caught the eye of the King of the beasts, and he claims her to be the other half of his soul. Resistance seems futile, but she must endure if she wishes to see her father again.
