From J-Novel Club:
To protect those she cares about from danger, Myne abandons the life she knows to become Rozemyne, the archduke’s mana-rich adopted daughter. But her passion for books hasn’t changed, nor does she hesitate to charge into another strange new world. In this biblio-fantasy by bookworms, for bookworms, the detailed setting continues to expand and so too does the book-making industry.
