The Gang Leaders Daughter

Alex Wolfe is the baby sister of two protective brothers and the daughter of a gang leader. Which gang? Only the strongest one in North America, The Devils. She may be a daddy's girl, and her father may be extremely protective of her; but that doesn't stop her from being reckless and getting into trouble. She gets arrested, smokes, and drinks. She seems to always be out at parties dancing her heart out and leaving strangers houses hungover the next morning.
Kyle Knight is the new head of his fathers gang, the second strongest in North America, The Knights. He's extremely sophisticated and mature, having to take over because of an emergency, he was forced to grow up fast. When he takes a trip to make a treaty with The Devils, he's introduced to the breathtaking Alex Wolfe. He's extremely fascinated, but unimpressed at her hungover state.
What happens when Kyle reads the 'conditions' of the treaty to Alex's father and brothers?
What will become of the two opposites?
