Rejected Luna Is the Alpha Queen

Werewolf packs are run by an Alpha, and the Alpha's mate carries the title of Luna. Rogues wiped out the Moonshadow Pack. One of its warriors, Arya, came out of it alive with a power far bigger than anyone around her knows about, and her mother's dying wish was that she keep it hidden. She marries Alpha Micah and does. Micah goes off to war and comes back with a new mate, Vera. He wants Arya to share the Luna title with her. Vera, Micah and his family treat her badly enough that she leaves. Once she is out of his house she lets the White Wolf loose, and with Lowe, the Lycan King, beside her she starts taking back what belonged to her. It is after the separation that she finds out what Vera is. On top of taking Micah, Vera is the traitor who killed Arya's parents and had the Moonshadow Pack slaughtered. Arya makes for the battlefield to face the people who betrayed her, and on the way there she falls in love with Lowe.
