Elena struggles to deal with a new discovery about her past. Clay readies Stonehaven for a possible attack from the Spanish by calling in new Pack members. Little does he know that one of them is a traitor. Meanwhile, Jeremy and Nick find a clue at the Spanish hideout that ultimately leads to them rushing back to Stonehaven.
Elena Michaels is the world's only female werewolf, who is forced to take on life-threatening responsibilities, in a male dominated world. The werewolves are monitored by The Pack, a powerful, organized werewolf family based in the grand manor of Stonehaven, the place where Elena's life as a werewolf began.
When a dead girl is discovered in the woods outside the town of Bear Valley (the adopted home of The Pack), it's the genesis of an all-out war against a rogue group of Mutts (non-Pack werewolves) whose aim is to destroy The Pack.
Torn between the new life she's created in Toronto and loyalty to her Pack family, Elena will fight her own battle between the woman, and the wolf within.
