Badass Alpha and.... Badass Luna?

Nikki has been abused most of her life. Ever since her mother left the abusing man he once called her husband. You read books about abused girls being shy, quiet and lonely, but Nikki is the exact opposite. She parties, she drink, she smokes, she fights; she does everything in her power to make people scared of her. Easton is also a total and complete badass, but he was basically born that way. He was born into power, being the alphas son, and current alpha of the strongest pack in the world. When he finds out Nikki is his mate, he is less than thrilled because he realizes that he will challenge him and his authority every day of their lives.
