When she woke up, she was in a parallel world...

An avid bookworm and college student Motosu Urano ends up dying in an unforeseen accident. This came right after the news that she would finally be able to work as a librarian like she had always dreamed of.

When she regained consciousness, she was reborn as Main, the daughter of a poor soldier. She was in the town of Ehrenfest, a town that existed in a parallel world and had a harsh class system where the magic-wielding nobles ruled supreme. But Main doesn't really let that get to her. After all, as long as she had books, she didn't really need anything else.

However, this world had a very low literacy rate and no real way of printing books, so books were scarce and belonged only to the nobles. They were completely out of reach for the daughter of some poor soldier. But that doesn't stop Main from wanting to read books, so she makes a decision…

"If there aren't any books, I'll just create some."

Main might not have energy or money, but she has an endless amount of knowledge from all the books she read in her previous life. Will Main actually be able to make some books? Main's adventure to create books starts now.[3]
