The intertwining of real historical events with fantastical elements creates a vivid world. I'm curious what inspired the author to blend these genres in this way.

The characters' struggles with belief felt so authentic and relatable despite the fantastical setting. Did others find themselves questioning what they believe in after reading?

The setting feels so well-researched and immersive. I wonder how much of the historical background was planned from the start versus developed during writing.
