In Maggie Stiefvater's Shiver, Grace and Sam found each other. In Linger, they fought to be together. Now, in Forever, the stakes are even higher than before. Wolves are being hunted. Lives are being threatened. And love is harder and harder to hold onto as death comes closing in. Then When Sam met Grace, he was a wolf and she was a girl. Eventually he found a way to become a boy, and their love transformed from curious distance to the intense closeness of shared lives. Now That should have been the end of their story. But Grace was not meant to stay human. Now she is the wolf. And the wolves of Mercy Falls are about to be hunted in one final, spectacular kill. Forever Sam would do anything for Grace. But can one boy and one love really change a hostile, predatory world? The past, the present, and the future will all collide in one pure moment — a moment of death or life, farewell or forever.
