The Events of Winter
While everyone is snowed in by the harsh winter, Myne has a plan: a plan to craft pseudo-papyrus as the first step towards making a book. Meanwhile, Eva teaches Turi a bunch of skills in order to prepare her for her upcoming baptism in the summer. Myne is told to think about where she wants to apprentice, but as always, books are the only thing on her mind. As winter rolls on, however, the family bonds and grows closer together, and Myne hits upon the perfect gift to give Turi to wear on her baptism day.

Ascendance of a Bookworm
When a sickly young girl suddenly becomes obsessed with inventing new things, her family and friends are all puzzled. "What has gotten into Myne?" they wondered, never dreaming that the answer is not a "What" but a "Who": Urano Motosu, a book-loving apprentice librarian who died in an earthquake in Tokyo who somehow found herself in Myne's body! And since Myne's world is still in a medieval stage, where books can only be owned by the elite, the new Myne intends to do everything she can to bring her beloved books to the masses in the time she has left.
