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 sees the gathering as a chance to wipe out every last werewolf. Seth is about to graduate high school when his mother, Eleanor, convinces him to go on the final hunt. He secretly plans to save Rylie and his werewolf brother, Abel, even if he has to turn against his fellow hunters to do it. What he doesn't realize is that Rylie has already decided on her own endgame: If the call doesn't lead to a cure, she's surrendering herself to the hunters. One way or another, everything is about to end in the dark forests of Gray Mountain--whether it means Rylie's liberation or the end of her life...
