The Burning Page by Genevieve Cogman

Spoiler

The farther I get into this series, the less I feel I can say in the face of compounding spoilers. I will say I'm deeply appreciative of the less tense point this particular volume ended on, and hopeful about a certain relationship dynamic. If you want fantasy and adventure with believable interpersonal tension and a sprinkle of interoffice and interworld politics then I highly recommend giving the series a try.
