To survive in a world that casts out those who are different, werewolves have one cardinal rule - to protect the pack, they must conceal their true identities. Their life depends on it.

Madison has become an expert at that. When she's not in school, she tries to keep her interactions with humans to a minimum. After all, such a big secret makes it almost impossible to keep up with friends, and the protection of her pack is her top priority.

As the pack hunts for the killer, Madison is left to protect the innocent people of her town from the ever-increasing danger. To do that, she must partner with new allies—but can they be trusted?
