Sarah Stilinski has basically gone through hell and back. Six months ago her life was ripped from her after her parents died in a fatal car crash. That led to her moving to Beacon Hills to live with her uncle and cousin, Stiles. She didn't even have time to mourn for her parents because she was dragged in to the supernatural mess. She had to watch as Stiles was possessed by the nogitsune and watched one of her best friends die right in front of her. And let's not forget the numerous times she was almost killed.
Now everything has calmed down and she has made through the first half of her freshman year with Stiles, Scott and everyone else by her side. Everything seems to be going fine now and for Sarah it is. That is until she notices a new kid and he seems to take an interest in her.
