Meet Mia McCall. She's the sister of the lacrosse star and the alpha werewolf, Scott McCall. After making her way to the first line of the lacrosse team, something isn't quite right. Not only is she the first girl to join the team, but on top of that, she's unbelievably fast and incredibly strong. Scott has never even thought about giving her sister 'The Bite', and the only werewolf she's ever known is Scott and Derek. So is there more to werewolves than meets the eye? And what does this mean for Mia's future?
