Brendon is a werewolf, a creature who can turn himself into canine form at will. Spencer is just a lonely guy trying to make it in LA. They come together when Brendon abandons his pack and finds a place to start a new life just when Spencer decides to start living his again after a painful loss.

Stiles runs away during his first heat, right into the waiting and ambiguously scary arms of the Alpha's nephew, Derek Hale. He doesn't have any choice except to submit, but along the way, he digs up a mystery that threatens his family and even the town's safety.
