Ascendance of a Bookworm: Part 2 Volume 1 by Miya Kazuki

With her baptism ceremony complete, Myne begins work in the temple as an apprentice shrine maiden.

Awaiting within is what she always wanted: a room full of books! But her new life isn’t quite the dream she was hoping for; she’s surrounded by nobles who scorn her common origins, and even her own servants are causing her trouble. On top of that, she has to constantly battle the weakness of her own body. But with a love for books burning in her heart, Myne gives her all to her new apprentice duties. Thus begins part two of this biblio-fantasy!
