Urano Motosu's lifelong dream to become a librarian comes true. Luck is not on her side, however, as a plethora of books falls on her during an earthquake. On the verge of death, she begs God to be reborn surrounded by nothing but books.

Her wish is fulfilled, albeit not how she expected: Urano is reincarnated as Myne—a sickly five-year-old child with an ardent desire to read—in another world where the upper class controls knowledge, and only the privileged have access to written works. As a commoner, Myne is distraught that she will never be able to find what she is yearning for.

To obtain books, Myne decides she should make them herself. Currently, she is but a kid thrust into an unknown place—but nothing will not stop Myne from achieving her goal.
