Werewolves are disappearing all over the country, and nobody's quite sure why. Kyla was forced to leave behind everything she cared about when her parents' ranch went bankrupt. With all of her friends and her boyfriend so far away, she isn't sure she'll ever feel as comfortable in this new life as she did in the old. Unaware of the danger, reclusive werewolf, Camille, couldn't be happier to make the new girl feel right at home in the small farm-town of Tranquility, California. By the time Kyla realizes there's something hiding out in the dark, watching her, she's unwittingly stepped into the crosshairs of a dangerous werewolf. Original target? Camille. Can the girls take down the threat before they become the latest victims of his deadly game?

Adjusting hasn't been easy for Kyla in her new life as a werewolf. After a nearly catastrophic loss of control, her and Camille decide to get help from the Pack in Oregon. The girls soon learn that human kidnappings have been on the rise, and Otherworld overseers from the Supernatural Council think that whatever is committing the crimes might be coming for the Pack next. Even with the help of a potential ally in a clan of vampires, the Pack can't determine why they've been targeted. It's a race against time as the abductions get closer and closer to home. And when Camille and Kyla find themselves at the center of the turmoil, they discover just how vast and dangerous their supernatural world really is.

Kyla wanted to stay with the Pack in Oregon to try helping people, but a recent series of murders involving ritualistic symbols is more than Camille bargained for when she agreed. As the case gets closer to home, overcoming her aversion to magic might be the only option alongside Kyla's determination to prevent more murders. With the help of Camille's sister, Luna, and the Supernatural Council's case lead, Abby, Camille and Kyla are on the hunt for a killer.

Summer's almost over, and the wolves and Abby are excited to start a new school year. But things don't go as planned, and Camille and Luna get targeted for experimentation with a deadly serum that turns werewolves rabid. As the serum forces Camille to confront the darkest parts of herself, the others find rising conflicts in different aspects of their own lives. The rush to save Camille and Luna from the serum will bring them all closer, but the decisions they have to make in order to survive will have lasting, dire consequences.
