Betrayed by the Moon by MJ Compton

With their packs’ very existence at stake, can two fated mates find the courage to love?
For generations, werewolves have lived under the protection of service-for-sanctuary treaties with the government. Now amid growing unrest there is a movement to abolish those treaties, risking the survival of werewolves everywhere.
Werewolf Ethan Calhoun’s mission to save the treaties means winning a powerful congressman’s support. He never expected to meet his life mate—and to discover she’s engaged in a life or death battle with the same politician.
Despite knowing she and Ethan are fated to be together, Selena Wolfe believes she’s too damaged to ever be anyone’s mate. As they fight to save her pack, Selena wrestles her need for Ethan while he struggles to win her trust.
Working together they must confront an evil Ethan never imagined and Selena can never forget.
