At Hoshinoka Academy, an isolated boarding school buried deep in the mountains, a mysterious new student arrives. Reina Kisaragi is beautiful, perfect—impossible. Everyone who meets her becomes obsessed, drawn to her in ways they can’t explain. But when a group of students finds an old yearbook, they uncover something chilling: Reina has been here before. Decades ago. Looking exactly the same. As their friends fall under her spell, the ones who resist begin to disappear. Something is very wrong with Reina. And the closer they get to the truth, the harder it is to escape her. Because she never lets go.
