Tohko Amano is a perfectly ordinary Book Girl-she lovesstories so much that she devours them. But some stories are too intenseeven for the specialists. Mysterious coded messages start to appear hintingthat a ghost is stalking the school, and what can Tohko do but try to defendthe book club from it? She's the president, even if she is a little . . . terrified.
But when the ghost turns out to be a real girl with twosouls, hovering on the edge of life and death, light and darkness, love andhatred, the Book Girl's skills-and those of Konoha, the trusty, level-headedWatson to her Sherlock Holmes-might be the only way to solve the mystery.
