Three best friends. One night in the woods. One scratch. One bite. Three worlds turned upside down. And as far as the supernatural went, sixteen year old Casey McCall didn't believe a thing. Being best friends with the one and only, Lydia Martin and having straight A's since kindergarten-she didn't have time to bury her face in crazy fairy tales. That is until her twin brother, Scott McCall, and herself were dragged into the woods by their best friend since preschool and Casey's undying crush, Stiles Stilinski. A strange wolf like creature bit Scott and scratched Casey, leaving them to figure out what the hell was happening to them and why they were suddenly believing in werewolves. But Casey isn't what she seems to be, visions and weird dreams begin to control-that and the fact that she only seems to be a werewolf when Scott looses control. That and how she befriends the untrustful Derek Hale, Casey can't seem to catch up. As things begin to spiral down, Casey finds herself loosing control in her feelings for Stiles and struggling not to break down in the middle of the supernatural. What is she? Why was she scratched? And why the hell does she keep having visions of the future? Why the hell was Stiles acting so strangely towards her? Why can't she seem to keep things under control? Maybe they were just a little Dysfunctional.
