It's been almost a year since Rylie Gresham was bitten by a werewolf on Gray Mountain. Now something is beckoning her back to the place she was attacked, along with every other werewolf in the world. But they aren't the only ones heeding the call. A group of hunters notices them gathering and sees it as their chance to wipe out the entire species.
Seth is about to graduate high school when he learns of the final hunt. He secretly plans to save Rylie and his werewolf brother even though he has to play along with the hunters to do it. But Rylie doesn't want to be saved. She's already decided to solve her problems with a silver bullet if answers aren't waiting on Gray Mountain.
