As the last known survivor in a powerful line of werewolves, Callum Elliott stands as the final line of defense against a dangerous enemy pack that does not see the value in human life. When his wife becomes pregnant, Callum must choose between his roles of the protector for many, or of his new family.  In favor of a slight hope of offering his daughter a normal human life, Callum leaves his old mission in the hands of a chosen successor.  When that man returns in need of his help, Callum finds himself precariously juggling two very separate worlds. As hard as he tried to hide from his destiny, Callum has allowed his past to catch up to him – now he must find a way to keep his daughter safe for good.
