There’s no time to rest—there are books to print!

Despite being separated from her lower city friends, Rozemyne is too busy to grieve. Her first year at the Royal Academy is over, and there’s much for her to do as the seasons change. She strives to continue making books like she promised Lutz, but the spring feast brings with it an important announcement—her engagement to Wilfried, a political move that should help to further resist influence from the top-ranking duchies...

Rozemyne makes magical ink with Ferdinand, fills the Central District with mana during Spring Prayer, and finds herself accidentally reviving an ancient ritual in Haldenzel. In the background, other provinces continue to grow, and the lower city is extensively remodeled in the name of developing the duchy as a whole.

Blessed be the melting of the snow! Prosperous be the duchy! Celebrate the coming of spring with this volume of this biblio-fantasy!
