Konoha Inoue writes short stories every day so club president Touko Amano, who calls herself a "literary girl" and eats the pages of books she loves, has something to devour after school. Their routine changes when classmate Chia Takeda asks Konoha to ghostwrite love letters to an upperclassman on the archery team, Shuji Kataoka, setting off a chain of events that draws the literature club into a mystery neither of them expected. This manga adapts the first Book Girl light novel.
