Elena has settled into a somewhat normal existence, living with her architect boyfriend and ignoring her wolf side as much as possible. However, she learns that her Pack (the governing body of werewolves) is in trouble and comes to their aid, flying to Stonehaven, the country estate of the pack Alpha. It is in Bear Valley, a fictional city in up-state New York. When Elena arrives, she is greeted by her ex-lover, Clayton Danvers, who bit her and made her a werewolf (without her consent). Clayton is also the bodyguard and foster-son to Jeremy Danvers, the pack Alpha (leader). Elena learns that a local woman was found murdered on Stonehaven's land, savaged by what authorities thought to be a dog. However, the Pack has determined that she was murdered by a Mutt, a rogue werewolf. They find out he is a recently escaped killer who was recently turned into a werewolf. Clay and Elena chase him into a rave and after several of the partygoers are killed, the wolf is hit by an SUV.
