[Machine Translation] One day, the mirror in her room suddenly began to shine before the eyes of "Kokoro," who had lost her place at school and had been shutting herself away. One day, the mirror in her room suddenly began to glow. There, a girl wearing a wolf mask awaited them, and seven people in similar circumstances, including Kokoro, were gathered there. They are told that their wishes will be granted if they find a key hidden in the castle. When all is revealed, they are both surprised and deeply moved. Winner of the Honya Taisho Award.

学校での居場所をなくし、閉じこもっていた“こころ”の目の前で、ある日突然部屋の鏡が光り始めた。輝く鏡をくぐり抜けた先にあったのは、城のような建物。そこにはオオカミの面をつけた少女が待ち受け、こころを含め、似た境遇の7人が集められていた。城に隠された鍵を探すことで願いが叶えられるという。すべてが明らかになるとき、驚きとともに大きな感動に包まれる。本屋大賞受賞作。
