A brilliant, book-obsessed girl pushes forward her fledgling printing and publishing venture in a medieval city, solving technical and logistical problems, recruiting and training staff, and fighting to secure scarce materials and market access. As she experiments with new formats and expands readership, she must navigate guild politics, aristocratic expectations, and rival interests while managing her fragile health and protecting the unusual knowledge that makes her work possible.
