Ascendance of a Bookworm

A frail young girl suddenly fixates on inventing new things, leaving her family and friends puzzled. 'What has gotten into Myne?' they wonder, never imagining that the answer is not a 'What' but a 'Who': Urano Motosu, a book-loving apprentice librarian who died in an earthquake in Tokyo and somehow inhabits Myne's body. In a medieval world where books remain the privilege of the elite, the new Myne resolves to do whatever it takes to bring her beloved books to the masses in the time she has left.
