Ascendance of a Bookworm (本好きの下剋上 Honzuki no Gekokujō) is is a Japanese fantasy light novel series written by Miya Kazuki and illustrated by Yō Shiina. It was serialized online between September 2013 and March 2017 on the user-generated novel publishing website Shōsetsuka ni Narō. It was later acquired by TO Books, who have published twenty-two volumes since March 2020.


The story centers around Urano, an early-20s Japanese soon-to-be librarian who dies in an earthquake, being ironically crushed by the books she loves so much. Luckily, she gets reincarnated in another world as a young girl named Main (Myne in Eng. ver.) but learns that books are scarce and only provided to prestigious elites. Main (retaining her memories from her previous life) decides to create and print her own books so that she can read again.
