Myne had been steadily growing used to the life in the temple, but just as she thought everything was going to go well, she learned the templed housed a significant number of starving, emaciated orphans. She agonized over the problem, then resolved to become the orphanage director and improve their lives herself. And so the Myne Workshop's temple branch began operation. This is a bibliofantasy by bookworms, for bookworms!
