Humans weren't always oblivious to the existence of werewolves. Estrella Hunter is one of the few humans aware of the existence of werewolves. She comes from a long line of assassins specially trained to go after them, and is more than ready for the day she completes her training and is appointed a task. When she is finally given a task, she finds herself determined to prove her worth. Alpha Ace Miller is one of the most powerful alphas in the country. He took on the post of alpha at the mere age of eighteen following the death of his father, and although young, he soon rose to become one of the most feared and respected leaders in existence. When these two figures clash, sparks fly.
