Humanity is on the brink of war-a war which threatens to destroy human kind, and yet they remain blissfully unaware.However, the Shifters know it-the ones who turn with the waxing and waning of the full moon. Those from the Underworld know it-the ones who spread chaos and murder. And the Hunters know it-the mortals cursed with the burden of knowledge, and the responsibility of protecting the human race.War is coming. One which doesn't belong to Jack, a Hunter bred with a gift, a weapon against the Supernatural kind, who is single-minded, and hell-bent on revenge against those who murdered his lover. And it's a war which doesn't belong to Kieran, a Werewolf sworn to no pack by choice, living a life of peace and quiet, away from the Supernatural community.When the pair are suddenly thrown together, forced to take sides against those who would destroy everything they hold dear, they must quickly re-learn what it means to be loyal. What it means to protect those they love. Working together, the pair must eliminate the greatest threat to their community either of them have ever known.
