‎A wolfless girl who was treated like an outcast in her former pack relocates to a new pack for a fresh start. She hopes to finally live a quiet life away from ridicule and rejection, but fate has other plans for her. She later discovers that the alpha of the pack, who is the heir to the Alpha King, is her destined mate. Scared of being rejected because she's wolfless, she keeps her distance while secretly searching for the truth behind her condition. She is eventually rejected by the alpha, which leaves her devastated, and she becomes determined to find out who she really is, why she is wolfless, and to prove to those who mocked her that she is not weak.‎‎What she discovers changes everything she thought she knew about herself. She is not just wolfless; she is the reincarnation of the Umbra Beast, an ancient entity feared for possessing powers capable of destroying the entire werewolf kingdom. A thousand years ago, the Umbra Beast was betrayed and sealed away by the ancestors of the alpha she is now fated to love. As her powers awaken, the kingdom's elders try to control her abilities for their own selfish gain. Torn between revenge and love, she must decide whether to destroy the bloodline that betrayed her or choose love with the alpha.‎‎Will she take revenge and rise as the ruler of the werewolf kingdom, or will she accept love and become the alpha's Luna?‎
