Scott's little sister, y/n is back in town to live with him and their mother. Although Scott notices something different about her. Her scent. It's not the same. Is she even human? If she isn't then what is she? Has she been like this all along? When y/n starts her first day of school she notices someone. Someone who she always despised. Someone who always wanted what y/n had. Malia Tate. Stiles is supposed to show y/n around the school but she hates him due to something that happened in the past. Although they end up in the same class and are forced to work on a project together. Enjoy :)
