Ascendance of a Bookworm

Crushed under an avalanche of books during an earthquake right after earning her librarian job, Urano Motosu wakes up inside sickly five-year-old soldier's daughter Myne in medieval Ehrenfest—where books belong strictly to mana-wielding nobles, so she decides to manufacture her own. Respects real supply chains, guild contracts, wood-pulp failures, and literacy economics instead of handing Myne instant magic shortcuts. Expands organically from cramped lower-city tenement family life to temple orphanage reform and cutthroat Ehrenfest noble politics. Writes Myne's bond with soldier father Gunther, seamstress mother Effa, sister Tuuli, merchant Benno, and High Priest Ferdinand with deep warmth. Upgrades to Wit Studio production values as Myne enters noble society in Part 3.
